240 KByte Flash Module (S12FTMRG240K2V1)
Upon clearing CCIF to launch the Read Once command, a Read Once phrase is fetched and stored in the
FCCOB indexed register. The CCIF flag will set after the Read Once operation has completed. Valid
phrase index values for the Read Once command range from 0x0000 to 0x0007. During execution of the
Read Once command, any attempt to read addresses within P-Flash block will return invalid data.

31.4.6.5 Program P-Flash Command
The Program P-Flash operation will program a previously erased phrase in the P-Flash memory using an
embedded algorithm.
CAUTION
A P-Flash phrase must be in the erased state before being programmed.
Cumulative programming of bits within a Flash phrase is not allowed.

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.
