Programming/Erasing Procedures
For a bulk erase:
1. Set LATCH = 1, CPEN = 1, ER1 = 1, and ER0 = 1.
2. Write to any address in the array.
3. Set EEPGM for a time, t_EBULK.
To terminate the programming or erase sequence, clear EEPGM, delay
for a time, t_FPV, to allow the programming voltage to fall, and then clear
LATCH and CPEN to free up the buses. Following each erase or
programming sequence, clear all programming control bits.
