2.5 Hardware Security Module Differences

AM263P devices come with two changes to the Hardware Security Module (HSM). The first is that the dedicated RAM for the HSM is increased from 192kB on AM263 devices to 256kB on AM263P devices.

Second, the HSM Watchdog Timer (WDT) is enabled by default in AM263P devices. With this change, the default clock source for the HSM WDT has been changed to RCCLK10M and the default timeout is set to 25 milliseconds.
