Memory and Registers
EEPROM
The 160 byte block of EEPROM is located at address $0100 to $019F.
The EEPROM can be programmed on a single-byte basis by
manipulating the EEPROM programming register at $001C. The voltage
necessary for programming and erasing the internal EEPROM is
generated by an on-chip charge pump. No external programming
voltage is necessary.
NOTE:
The erased state of an EEPROM cell is ‘1’. This means that a write
forces zeroes to the bits specified, whilst bits defined as ones are
unchanged by the write operation.

register (EPROG)
CPEN — Charge pump enable
1 = The charge pump, which produces the internal programming
voltage for the EEPROM, is enabled; the programming voltage
is available as soon as the EEPGM bit is set. The EELATCH
bit should also be set in order that programming can take
place.
0 = The charge pump is disabled.
This bit should always be cleared when the charge pump is not in use.
ER1–ER0 — Erase select bits
ER1 and ER0 form a 2-bit field which is used to select one of three
erase modes: byte, block or bulk. Table 2 shows the modes selected
for each bit configuration.
In byte erase mode, only the selected byte is erased. In block erase
mode, a 32-byte block of EEPROM is erased (the EEPROM memory
