EPROM and EEPROM
12.10 Operation in Stop Mode and Wait Mode
Advance Information
130
For a bulk erase:
To terminate the programming or erase sequence, clear EEPGM, delay
for a time, t
EELAT and CPEN to free up the buses. Following each erase or
programming sequence, clear all programming control bits.
The RC oscillator for the EEPROM is disabled automatically when
entering stop mode. To help conserve power, the user should disable
the RC oscillator before entering wait mode.
1. Set EELAT = 1, CPEN = 1, ER1 = 1, and ER0 = 1.
2. Write to any address in the array.
3. Set EEPGM for a time, t
FPV,
EPROM and EEPROM
to allow the programming voltage to fall, and then clear
EBULK
