PROM Mode Pin Functions
V
PP
:
Applies the programming voltage (12.5 V
±
0.3 V) to the built-in PROM.
CE
:
Inputs a control signal to enable PROM programming and verification.
OE
:
Inputs a data output control signal for verification.
A
0
–A
14
:
Act as address input pins of the built-in PROM.
O
0
–O
7
:
Act as data bus input pins of the built-in PROM. Each of O

has two pins; before using these
pins, connect each pair together.
M

M
1
, RESET,
TEST
:
Used to set PROM mode. The MCU is set to the PROM mode by pulling
