I/O type

Input/output

I/O port P6

P60 to P63,

P67

This is an 5-bit I/O port equivalent to P0. When set for input in single-

chip, microprocessor and memory expansion modes, the user can

specify in units of four bits via software whether or not they are tied to a

pull-up resistor. Pins in this port also function as UART0 and multi-

master I2C-BUS interface 0 I/O pins as selected by software.

Input/output

I/O port P7

I/O port P9

I/O port P10

P70 to P77

P90 to P94

P102 to P107

This is an 8-bit I/O port equivalent to P6 (P70 and P71 are N-channel

open-drain output). Pins in this port also function as timers A2 and A3,

UART2, multi-master I2C-BUS interface 0, or HSYNC counter I/O pins as

selected by software.

This is an 5-bit I/O port equivalent to P6. Pins in this port also function

as Timer B0 to B2 input pins, D-A converter output pins, or multi-master

2C-BUS interface 1 I/O pins, RXD2, and TXD2 pins. P92 can be set

using software to function as the R0 outout pin of digital RGB output.

This is an 6-bit I/O port equivalent to P6. Pins in this port also function

as A-D converter input pins. P105 to P107 can be set using software to

function as the B2, G2, and R2 outout pins of digital RGB output.

Input/output

I/O port P8

P82, P83,

P86, P87

P82, P83, P86 and P87 are I/O ports with the same functions as P6.

Using software, P82 and P83 can be made to function as the I/O pins for

the input pins for external interrupts. P86 and P87 can be set using

software to function as the I/O pins for a sub-clock generation circuit,

and B0 output pins of digital RGB output. In this case, connect a

quartz oscillator between P86 (XCOUT pin) and P87 (XCIN pin).

This is an OSD clock output pin.

Input composite video signal through a capacitor.

Connect a capacitor between VHOLD and Vss.

Connect a filter using of a capacitor and a resistor

between HLF and Vss.

This is a test input pin. Fix it to “L.”
