+ * @brief Cryptography accelerator peripheral API
+ *
+ * @details
+ * In order for cryptographic support, users are recommended to consider the
+ * crypto APIs of the mbedTLS library provided by Silicon Labs instead of the
+ * interface provided in em_crypto.h. The mbedTLS library provides a much
+ * richer crypto API, including hardware acceleration of several functions.
+ *
+ * The main purpose of em_crypto.h is to implement a thin software interface
+ * for the CRYPTO hardware functions especially for the accelerated APIs of
+ * the mbedTLS library. Additionally em_crypto.h implement the AES API of the
+ * em_aes.h (supported by classic EFM32) for backwards compatibility. The
+ * following list summarizes the em_crypto.h inteface:
+ * @li AES (Advanced Encryption Standard) @ref crypto_aes
+ * @li SHA (Secure Hash Algorithm) @ref crypto_sha
+ * @li Big Integer multiplier @ref crypto_mul
+ * @li Functions for loading data and executing instruction sequences @ref crypto_exec
+ *
+ * @n @section crypto_aes AES
+ * The AES APIs include support for AES-128 and AES-256 with block cipher
+ * modes:
+ * @li CBC - Cipher Block Chaining mode
+ * @li CFB - Cipher Feedback mode
+ * @li CTR - Counter mode
+ * @li ECB - Electronic Code Book mode
+ * @li OFB - Output Feedback mode
+ *
+ * For the AES APIs Input/output data (plaintext, ciphertext, key etc) are
+ * treated as byte arrays, starting with most significant byte. Ie, 32 bytes
+ * of plaintext (B0...B31) is located in memory in the same order, with B0 at
+ * the lower address and B31 at the higher address.
+ *
+ * Byte arrays must always be a multiple of AES block size, ie. a multiple
+ * of 16. Padding, if required, is done at the end of the byte array.
+ *
+ * Byte arrays should be word (32 bit) aligned for performance
+ * considerations, since the array is accessed with 32 bit access type.
+ * The core MCUs supports unaligned accesses, but with a performance penalty.
+ *
+ * It is possible to specify the same output buffer as input buffer as long
+ * as they point to the same address. In that case the provided input buffer
+ * is replaced with the encrypted/decrypted output. Notice that the buffers
+ * must be exactly overlapping. If partly overlapping, the behavior is
+ * undefined.
+ *
+ * It is up to the user to use a cipher mode according to its requirements
+ * in order to not break security. Please refer to specific cipher mode
+ * theory for details.

+ * @n @section crypto_sha SHA
+ * The SHA APIs include support for
+ * @li SHA-1 @ref CRYPTO_SHA_1
+ * @li SHA-256 @ref CRYPTO_SHA_256
+ *
+ * The SHA-1 implementation is FIPS-180-1 compliant, ref:
+ * @li Wikipedia - SHA-1, https://en.wikipedia.org/wiki/SHA-1
+ * @li SHA-1 spec - http://www.itl.nist.gov/fipspubs/fip180-1.htm

+ * @li SHA-2 spec - http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf
+ *
+ * @n @section crypto_mul CRYPTO_Mul
+ * @ref CRYPTO_Mul is a function for multiplying big integers that are
+ * bigger than the operand size of the MUL instruction which is 128 bits.
+ * CRYPTO_Mul multiplies all partial operands of the input operands using
+ * MUL to form a resulting number which may be twice the size of
+ * the operands.
+ *
+ * CRPYTO_Mul is typically used by RSA implementations which perform a
+ * huge amount of multiplication and square operations in order to
+ * implement modular exponentiation.
+ * Some RSA implementations use a number representation including arrays
+ * of 32bit words of variable size. The user should compile with
+ * -D USE_VARIABLE_SIZED_DATA_LOADS in order to load these numbers
+ * directly into CRYPTO without converting the number representation.
+ *
+ * @n @section crypto_exec Load and Execute Instruction Sequences
+ * The functions for loading data and executing instruction sequences can
+ * be used to implement complex algorithms like elliptic curve cryptography
+ * (ECC)) and authenticated encryption algorithms. There are two typical
+ * modes of operation:
+ * @li Multi sequence operation
+ * @li Single static instruction sequence operation
+ *
+ * In multi sequence mode the software starts by loading input data, then
+ * an instruction sequence, execute, and finally read the result. This
+ * process is repeated until the full crypto operation is complete.
+ *
+ * When using a single static instruction sequence, there is just one
+ * instruction sequence which is loaded initially. The sequence can be setup
+ * to run multiple times. The data can be loaded during the execution of the
+ * sequence by using DMA, BUFC and/or programmed I/O directly from the MCU
+ * core. For details on how to program the instruction sequences please refer
+ * to the reference manual of the particular Silicon Labs device.
+ *
+ * In order to load input data to the CRYPTO module use any of the following
+ * functions:
+ * @li @ref CRYPTO_DataWrite - Write 128 bits to a DATA register.
+ * @li @ref CRYPTO_DDataWrite - Write 256 bits to a DDATA register.
+ * @li @ref CRYPTO_QDataWrite - Write 512 bits to a QDATA register.
+ *
+ * In order to read output data from the CRYPTO module use any of the
+ * following functions:
+ * @li @ref CRYPTO_DataRead - Read 128 bits from a DATA register.
+ * @li @ref CRYPTO_DDataRead - Read 256 bits from a DDATA register.
+ * @li @ref CRYPTO_QDataRead - Read 512 bits from a QDATA register.
+ *
+ * In order to load an instruction sequence to the CRYPTO module use
+ * @ref CRYPTO_InstructionSequenceLoad.
+ *
+ * In order to execute the current instruction sequence in the CRYPTO module
+ * use @ref CRYPTO_InstructionSequenceExecute.
+ *
+ * In order to check whether an instruction sequence has completed
+ * use @ref CRYPTO_InstructionSequenceDone.
+ *
+ * In order to wait for an instruction sequence to complete
+ * use @ref CRYPTO_InstructionSequenceWait.
+ *
+ * In order to optimally load (with regards to speed) and execute an
+ * instruction sequence use any of the CRYPTO_EXECUTE_X macros (where X is
+ * in the range 1-20) defined in @ref em_crypto.h. E.g. CRYPTO_EXECUTE_19.
