Write Protection Registers
To prevent any single software error that may corrupt PIO behavior, certain address spaces can
be write-protected by setting the WPEN bit in the
(PIO_WPMR).
If a write access to the protected registers is detected, then the WPVS flag in the PIO Write Pro-
tect Status Register (PIO_WPSR) is set and the field WPVSRC indicates in which register the
write access has been attempted.
The WPVS flag is reset by writing the PIO Write Protect Mode Register (PIO_WPMR) with the
appropriate access key, WPKEY.
The protected registers are:
