Reset Command
The reset command forces the ATAES132 to reset the logic, including the AES engine, nonce, and authentication status flag.
This command does not return a response.
When a Reset command is received, the ATAES132 performs the same power up reset sequence that occurs during wakeup
from the sleep state. The reset is complete after the WakeUp Ready time t
During the reset of an ATAES132 configured for SPI interface mode, the device will answer the SPI read status register
command with 0xFF to indicate it is "busy". When reset is complete, the WIP status bit changes to 0b to indicate the device is
in the active state. The ATAES132 will only accept the SPI read status register command while it is resetting – all other
commands will be ignored. The SPI read status register command is described in Section K.3.6.

reset. The ACK poll reply will change to ACK when the device is in the active state. The ATAES132 will not accept any I
commands while it is "busy". ACK polling is described in Section J.3.8.
