After clearing CCIF to launch the Program Once command, the FTFL first verifies that
the selected record is erased. If erased, then the selected record is programmed using the
values provided. The Program Once command also verifies that the programmed values
read back correctly. The CCIF flag is set after the Program Once operation has
completed.
The reserved program flash IFR location accessed by the Program Once command cannot
be erased and any attempt to program one of these records when the existing value is not
Fs (erased) is not allowed. Valid record index values for the Program Once command
range from 0x00 to 0x0F. During execution of the Program Once command, any attempt
to read addresses within program flash returns invalid data.
1. If a Program Once record is initially programmed to 0xFFFF_FFFF, the Program Once command is allowed to execute
