EEPROM
Operation in Stop Mode and Wait Mode
For a bulk erase:
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, tEBULK.
To terminate the programming or erase sequence, clear EEPGM, delay
for a time, tFPV, to allow the programming voltage to fall, and then clear
EELAT and CPEN to free up the buses. Following each erase or
programming sequence, clear all programming control bits.
12.5 Operation in Stop Mode and Wait Mode
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.
