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.
4.40.4.5.5
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.
