Chapter 25 256 KByte Flash Module (S12XFTM256K2V1)
Upon clearing CCIF to launch the Program P-Flash command, the Memory Controller will program the
data words to the supplied global address and will then proceed to verify the data words read back as
expected. The CCIF flag will set after the Program P-Flash operation has completed.
25.4.2.7
The Program Once command restricts programming to a reserved 64 byte field (8 phrases) in the
nonvolatile information register located in P-Flash block 0. The Program Once reserved field can be read
using the Read Once command as described in
be issued once since the nonvolatile information register in P-Flash block 0 cannot be erased. The Program
