35.13 Write Protection Registers
6500C–ATARM–8-Feb-11
To prevent any single software error that may corrupt HSMCI behavior, the entire HSMCI
address space from address offset 0x000 to 0x00FC can be write-protected by setting the
WPEN bit in the
If a write access to anywhere in the HSMCI address space from address offset 0x000 to 0x00FC
is detected, then the WPVS flag in the HSMCI Write Protect Status Register (HSMCI_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 HSMCI Write Protect Mode Register (HSMCI_WPMR)
with the appropriate access key, WPKEY.
The protected registers are:
