Write Protection Registers
To prevent any single software error that may corrupt AIC behavior, the registers listed below
can be write-protected by setting the WPEN bit in the
(AIC_WPMR).
If a write access in a write-protected register is detected, then the WPVS flag in the
Protect Status Register
the write access has been attempted.
The WPVS flag is automatically reset after reading the AIC Write Protect Status Register.
The protected registers are:
