HAL_HASH_ContextSaving() function
Save the HASH context in case of processing suspension.
Syntax
Implemented in ![]()
stm32f4xx_hal_hash.c:1405
Return value
None
Notes
The IMR, STR, CR then all the CSR registers are saved in that order. Only the r/w bits are read to be restored later on. By default, all the context swap registers (there are HASH_NUMBER_OF_CSR_REGISTERS of those) are saved. pMemBuffer points to a buffer allocated by the user. The buffer size must be at least (HASH_NUMBER_OF_CSR_REGISTERS + 3) * 4 uint8 long.
