Chapter 28 768 KByte Flash Module (S12XFTM768K4V2)
28.4.2.4
The Read Once command provides read access to a reserved 64 byte field (8 phrases) located in the
nonvolatile information register of P-Flash block 0. The Read Once field is programmed using the
Program Once command described in
from the Flash block containing the Program Once reserved field to avoid code runaway.
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 0 will return invalid data.
