256 KByte Flash Module (S12XFTMR256K1V1)
18.4.2.6
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
Once command must not be executed from the Flash block containing the Program Once reserved field to
avoid code runaway.
Upon clearing CCIF to launch the Program Once command, the Memory Controller first verifies that the
selected phrase is erased. If erased, then the selected phrase will be programmed and then verified with
read back. The CCIF flag will remain clear, setting only after the Program Once operation has completed.
The reserved nonvolatile information register accessed by the Program Once command cannot be erased
and any attempt to program one of these phrases a second time will not be allowed. Valid phrase index
values for the Program Once command range from 0x0000 to 0x0007. During execution of the Program
Once command, any attempt to read addresses within P-Flash block 0 will return invalid data.
