Re-inits key and state after a sleep or TRX reset.
This function re-initializes the AES key and the state of the AES engine after TRX sleep or reset. The contents of AES registers AES_CON and AES_CON_MIRROR are restored, the next AES operation started with sal_aes_wrrd() will be executed correctly. However, the contents of SRAM buffers is destroyed, in general. When using sal_aes_wrrd(), call sal_aes_read() to get the result of the last AES operation BEFORE you put the transceiver unit to sleep state!
