64 KByte Flash Module (S12XFTMR64K1V1)
P-Flash phrase containing the D-Flash protection byte during the reset sequence, the DPOPEN bit will be
cleared and DPS bits will be set to leave the D-Flash memory fully protected.
Trying to alter data in any protected area in the D-Flash memory will result in a protection violation error
and the FPVIOL bit will be set in the FSTAT register. Block erase of the D-Flash memory is not possible
if any of the D-Flash sectors are protected.
20.3.2.11 Flash Common Command Object Register (FCCOB)
The FCCOB is an array of six words addressed via the CCOBIX index found in the FCCOBIX register.
Byte wide reads and writes are allowed to the FCCOB register.
