mbed_official 133:d4dda5c437f0 16 ##### How to use this driver #####
mbed_official 133:d4dda5c437f0 17 ==============================================================================
mbed_official 133:d4dda5c437f0 18 [..]
mbed_official 133:d4dda5c437f0 19 The CRC HAL driver can be used as follows:
mbed_official 133:d4dda5c437f0 20
mbed_official 133:d4dda5c437f0 21 (#) Enable CRC AHB clock using __CRC_CLK_ENABLE();
mbed_official 133:d4dda5c437f0 22
mbed_official 133:d4dda5c437f0 23 (#) Use HAL_CRC_Accumulate() function to compute the CRC value of
mbed_official 133:d4dda5c437f0 24 a 32-bit data buffer using combination of the previous CRC value
mbed_official 133:d4dda5c437f0 25 and the new one.
mbed_official 133:d4dda5c437f0 26
mbed_official 133:d4dda5c437f0 27 (#) Use HAL_CRC_Calculate() function to compute the CRC Value of
mbed_official 133:d4dda5c437f0 28 a new 32-bit data buffer. This function resets the CRC computation
mbed_official 133:d4dda5c437f0 29 unit before starting the computation to avoid getting wrong CRC values.
