The Program P-Flash operation will program a previously erased phrase in the P-Flash memory using an
embedded algorithm.
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.
