I/O
Serial data pin. Output port when reading and
input port when writing. Can be assigned as a
Input/push-pull output port.
I
Serial clock pin. Input only pin.
I
Power supply pin for EPROM cell writing
(indicates that OTP enters into the writing
mode). When 12.5 V is applied, OTP is in
writing mode and when 5 V is applied, OTP is in
reading mode. (Option)

OPERATING MODE CHARACTERISTICS
When 12.5 V is supplied to the V
PP
(TEST) pin of the KS88P6232, the EPROM programming mode is entered.
The operating mode (read, write, or read protection) is selected according to the input signals to the pins listed in
Table 16-3 below.
