1.6 Pin Description

Table 1.4 and 1.5 describe the available pins.

Table 1.4. Pin Description(1)

Pin name Signal name

I/O type

Function

VCC,VSS

Power supply

Apply 2.7V to 5.5V to the VCC pin, and 0V to the Vss pin.

input

CNVSS

Input

Connect this pin to Vss.

IVCC

Leave this pin open.

____________

RESET

Reset input

Input

"L" on this input resets the microcomputer.

XIN

Clock input

Input

These pins are provided for the main clock generating circuit input/output.

XOUT

Clock output

Output

Connect a ceramic resonator or crystal between the XIN and the XOUT pins.

To use an externally derived clock, input it to the XIN pin and leave the XOUT

pin open.

AVCC

Analog power

This pin is a power supply input for the A/D converter. Connect this

supply input

pin to VCC.

AVSS

Analog power

This pin is a power supply input for the A/D converter. Connect this

supply input

pin to VSS.

VREF

Reference

Input

This pin is a reference voltage input for the A/D converter.

Voltage input

P15~P17 I/O port P1

Input/

This is an 3-bit CMOS I/O port. It has an input/output port direction

output

When used for input, a pull-up resister option can be selected for the

entire group of three pins. Additional software selectable secondary

______

functions are: 1) P15 to P17 can be configured as external INT interrupt

pins, and; 2) P15 can input a trigger for the A/D converter.

P60~P67 I/O port P6

Input/

This is an 8-bit CMOS I/O port. It has an input/output port direction

output

When used for input, a pull-up resister option can be selected for the

entire group of four pins. Pins in this port also function as UART0 and

UART1 I/O.

P70~P77 I/O port P7

Input/

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

output

open-drain output) P7 can also function as I/O for timer A0 to A3, as

selected by software. Additional programming options are: P70 to P73 can

assume UART2 I/O capabilities, and P72 to P75 can function as output

pins for the three-phase motor control timer.

P80~P83, I/O port P8

Input/

P80 to P83 and P85 to P87 are an 7-bit I/O port equivalent to P6.When

P85~P87

output

used for input, a pull-up resister option can be selected for the entire

group of four pins or three pins. Additional software-selectable secondary

functions are: 1) P80 and P81 can act as either I/O for Timer A4, or as

output pins for the three-phase motor control timer; 2) P82 to P83 can be

______

_______ _____

configured as external INT interrupt pins; 3) P85 can be used as NMI/SD.

P85 can not be used as I/O port while the three-phase motor control is

enabled. Apply a stable "H" to P85 after setting the direction register for

P85 to "0" when the three-phase motor control is enabled, and; 4) P86 and

P87 can serve as I/O pins for the sub-clock generation circuit. In this latter

case, a quartzoscillator must be connented between P86 (XCOUT pin) and

P87 (XCIN pin).
