<> 144:ef7eb2e8f9f7 1 ================ Silicon Labs Peripheral Library ============================
<> 144:ef7eb2e8f9f7 2
<> 144:ef7eb2e8f9f7 3 This directory, "emlib", contains the Silicon Labs Peripheral Support
<> 144:ef7eb2e8f9f7 4 library for the EFM32 and EZR32 series of microcontrollers and System-On-Chip
<> 144:ef7eb2e8f9f7 5 devices.
<> 144:ef7eb2e8f9f7 6
<> 144:ef7eb2e8f9f7 7 Some design guidelines for this library:
<> 144:ef7eb2e8f9f7 8
<> 144:ef7eb2e8f9f7 9 * Follow the guidelines established by ARM's and Silicon Labs's adaptation
<> 144:ef7eb2e8f9f7 10 of the CMSIS (see below) standard.
<> 144:ef7eb2e8f9f7 11
<> 144:ef7eb2e8f9f7 12 * Be usable as a starting point for developing richer, more target specific
<> 144:ef7eb2e8f9f7 13 functionality (i.e. copy and modify further).
<> 144:ef7eb2e8f9f7 14
<> 144:ef7eb2e8f9f7 15 * Ability to be used as a standalone software component, to be used by other
<> 144:ef7eb2e8f9f7 16 drivers, that should cover "the most common cases".
<> 144:ef7eb2e8f9f7 17
<> 144:ef7eb2e8f9f7 18 * Readability of the code and usability preferred before optimization for speed
<> 144:ef7eb2e8f9f7 19 and size or covering a particular "narrow" purpose.
<> 144:ef7eb2e8f9f7 20
<> 144:ef7eb2e8f9f7 21 * As little "cross-dependency" between modules as possible, to enable users to
<> 144:ef7eb2e8f9f7 22 pick and choose what they want.

<> 144:ef7eb2e8f9f7 24 ================ About CMSIS ================================================
<> 144:ef7eb2e8f9f7 25
<> 144:ef7eb2e8f9f7 26 These APIs are based on EM_CMSIS "Device" header file structure.
<> 144:ef7eb2e8f9f7 27
<> 144:ef7eb2e8f9f7 28 As a result of this, the library requires basic C99-support. You might have
<> 144:ef7eb2e8f9f7 29 to enable C99 support in your compiler. Comments are in doxygen compatible
<> 144:ef7eb2e8f9f7 30 format.
<> 144:ef7eb2e8f9f7 31
<> 144:ef7eb2e8f9f7 32 The EM_CMSIS library contains all peripheral module registers and bit field
<> 144:ef7eb2e8f9f7 33 descriptors.
<> 144:ef7eb2e8f9f7 34
<> 144:ef7eb2e8f9f7 35 To download EM_CMSIS, go to
