NOTES:
Algorithm for Programming
a Row (32 Bytes) of FLASH Memory
The time between each FLASH address change (step 7 to step 7 loop),
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.
