M37272M6H/M8H/MAH/MFH–XXXSP/FP

M37272E8SP/FP, M37272EFSP/FP

SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER with CLOSED CAPTION DECODER

and ON-SCREEN DISPLAY CONTROLLER

Ports P00–P05

Data bus

Direction register

Port latch

Ports P1, P2, P30, P31

Direction register

Data bus

Port latch

N-channel open-drain output

Ports P00–P05

Note : Each port is also used as follows :

P00–P05 : PWM0–PWM5

CMOS output

Ports P1, P2, P30, P31

Notes 1: Each port is also used as follows :

P10 : OUT2

P20 : SCLK

P11 : SCL1

P21 : SOUT

P12 : SCL2

P22 : SIN

P13 : SDA15

P23 : TIM3

P14 : SDA2

P24 : TIM2

P15 : AD1/INT3 P30 : AD5

P16 : AD2

P31 : AD6

P17 : AD3

2: The output structure of ports P30 and P31 can be selected either CMOS output or N-channel open-

drain output structure (when selecting N-channel open-drain, it is the same with P06 and P07).

3: The output structure of ports P11–P14 is N-channel open-drain output when using as multi-master

I2C-BUS interface (it is the same with P06 and P07).

4: The output structure of ports P20 and P21 is N-channel open-drain output when using as serial

output (it is the same as P06 and P07).
