Algorithm for programming
a row (32 bytes) of FLASH memory
NOTE:
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 step 10)
must not exceed the maximum programming
time, t
This row program algorithm assumes the row/s
to be programmed are initially erased.
