NOTE:
NOTE:
Programming of the FLASH memory is done on a row basis. A row
consists of 64 consecutive bytes starting from addresses $xx00, $xx40,
$xx80, or $xxC0. Use the following procedure to program a row of
FLASH memory.
algorithm.)
This program sequence is repeated throughout the memory until all data
is programmed.
The time between each FLASH address change (step 7 to step 7), or the
time between the last FLASH addressed programmed to clearing the
PGM bit (step 7 to step 10), must not exceed the maximum programming
time, t
Programming and erasing of FLASH locations cannot be performed by
code being executed from the FLASH memory. While these operations
must be performed in the order shown, other unrelated operations may
occur between the steps.
