I/O port P6

P50 to P57

P60 to P63,

P67

This is an 8-bit I/O port equivalent to P0. In single-chip mode, P57 in

this port outputs a divide-by-8 or divide-by-32 clock of XIN or a clock of

the same frequency as XCIN as selected by software.

Input

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, UART2 and

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

HOLD,

ALE,

RDY

Output WRL, WRH (WR and BHE), RD, BCLK, HLDA, and ALE

signals. WRL and WRH, and BHE and WR can be switched using

software control.

s WRL, WRH, and RD selected

With a 16-bit external data bus, data is written to even addresses

when the WRL signal is “L” and to the odd addresses when the WRH

signal is “L”. Data is read when RD is “L”.

s WR, BHE, and RD selected

Data is written when WR is “L”. Data is read when RD is “L”. Odd

addresses are accessed when BHE is “L”. Use this mode when using

an 8-bit external data bus.

While the input level at the HOLD pin is “L”, the microcomputer is

placed in the hold state. While in the hold state, HLDA outputs a “L”

level. ALE is used to latch the address. While the input level of the

RDY pin is “L”, the microcomputer is in the ready state.

P90 to P94

P100 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

I2C-BUS interface 1 I/O pins.

This is an 8-bit I/O port equivalent to P6. Pins in this port also function

as A-D converter input pins. Furthermore, P100 and P101 also function

as input pins for OSD function.

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. In

this case, connect a quartz oscillator between P86 (XCOUT pin) and P87

(XCIN pin).
