AESCommonLPF3 Hardware Attributes.
| uint8_t AESCommonLPF3_HWAttrs::intPriority |
Crypto Peripheral's interrupt priority.
The Low Power F3 devices use either three or two priority bits, depending on the device. That means ~0 has the same effect as (7 << 5) or (3 << 6), respectively.
Setting the priority to 0 is not supported by this driver.
HWI's with priority 0 ignore the HWI dispatcher to support zero-latency interrupts, thus invalidating the critical sections in this driver.
