Memory
2.5.5 FLASH Program Operation
Programming of the FLASH memory is done on a row basis. A row consists of 32 consecutive bytes
starting from addresses $XX00, $XX20, $XX40, $XX60, $XX80, $XXA0, $XXC0 or $XXE0. Use this
step-by-step procedure to program a row of FLASH memory:
Figure 2-4
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,

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.
