MC68HC05C5 Specification Rev. 1.2
To erase a byte of EEPROM, set LATCH = 1, CPEN = 1, ER1 = 0 and ER0 = 1, write to
the address to be erased, and set EEPGM for a time t
EBYT.
To erase a block of EEPROM, set LATCH = 1, CPEN = 1, ER1 = 1 and ER0 = 0, write to
any address in the block, and set EEPGM for a time t
EBLOCK.
For a bulk erase, set LATCH = 1, CPEN = 1, ER1 = 1, and ER0 = 1, write to any address
in the array, and 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 program 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.
