KEY - AES Key Register
INTCTRL - AES Interrupt Control Register
The Key Register is used to access the Key memory. Before encryption/decryption can take
place the Key memory must be written sequentially byte by byte through the Key Register. After
encryption/decryption is done the last subkey can be read sequentially byte by byte through the
Key Register.
Loading the initial data to the Key Register should be made after setting the appropriate AES-
mode and direction.
These bits are unused and reserved for future use. For compatibility with future devices, always
write these bits to zero when this register is written.
These bits enable the AES Interrupt and select the interrupt level as described in
”Interrupts and Programmable Multi-level Interrupt Controller” on page
rupt will be triggered when the SRIF in the STATUS register is set.
