Freescale Semiconductor
Algorithm for programming
a row (64 bytes) of FLASH memory
NOTES:
The time between each FLASH address change (step 7 to step 7) or
the time between the last FLASH address programmed to clearing
PGM bit (step 7 to step10) must not exceed the maximum
programming time, t
This row program algorithm assumes the row/s to be
programmed are initially erased.
