Programming and erasing of FLASH locations can not be performed by
code being executed from the same FLASH array.
While these operations must be performed in the order shown, other
unrelated operations may occur between the steps. Care must be taken
within the FLASH array memory space such as the COP control register
(COPCTL) at $FFFF.
It is highly recommended that interrupts be disabled during program/ erase
operations.
Do not exceed t
cumulative high voltage programming time to the same row before next
erase. t
Refer to
The time between programming the FLASH address change (step 7 to step
7), or the time between the last FLASH programmed to clearing the PGM
bit (step 7 to step 10) must not exceed the maximum programming time,
t
Be cautious when programming the FLASH array to ensure that
non-FLASH locations are not used as the address that is written to when
selecting either the desired row address range in step 3 of the algorithm or
the byte to be programmed in step 7 of the algorithm. This applies
particularly to $FFD4–$FFDF.
