Algorithm for programming
a row (64 bytes) of FLASH memory
NOTE:
The time between each FLASH address change (step 6 to step 6), or
the time between the last FLASH address programmed
to clearing PGM bit (step 6 to step 9)
must not exceed the maximum programming
time, t
This row program algorithm assumes the row/s
to be programmed are initially erased.
