• Description: Programming and Erasing FLASH and EEPROM Memories on the MC68HC908AS60A/AZ60A
• Manufacturer: Freescale Semiconductor / Motorola

Freescale Semiconductor, Inc.
Application Note
NOTE:
Programming and erasing of FLASH locations cannot be performed by
code being executed from the same FLASH array. However, code can
be executed out of one FLASH array to program/erase locations in the
other array.
While these operations must be performed in the order shown, other
unrelated operations may occur between the steps. Do not exceed
t
maximum or t
maximum. t
is defined in step 8. t
is
PROG

PROG
HV
defined as the cumulative time that high voltage is applied to the same
row before an erase.
