Chapter 29 128 Kbyte Flash Module (S12XFTX128K1V1)
29.4.2.3
The program operation will program a previously erased word in the Flash memory using an embedded
algorithm.
An example flow to execute the program operation is shown in
sequence is as follows:
If a word to be programmed is in a protected area of the Flash block, the PVIOL flag in the FSTAT register
will set and the program command will not launch. Once the program command has successfully launched,
the CCIF flag in the FSTAT register will set after the program operation has completed unless a new
command write sequence has been buffered. By executing a new program command write sequence on
sequential words after the CBEIF flag in the FSTAT register has been set, up to 55% faster programming
time per word can be effectively achieved than by waiting for the CCIF flag to set after each program
operation.
