NVMKEY<31:0>: Unlock Register bits
These bits are write-only, and read as ‘0’ on any read
NVMADDR<31:0>: Flash Address bits
Bulk/Chip/PFM Erase: Address is ignored.
Page Erase: Address identifies the page to erase.
Row Program: Address identifies the row to program.
Word Program: Address identifies the word to program.
This register is used as part of the unlock sequence to prevent inadvertent writes to the PFM.
