Description

Clock

control

OSC0

Input

This pin is for connecting a crystal oscillator. If an external

clock is used, supply it to this pin.

OSC1

Output

This pin is for connecting a crystal oscillator. If an external

clock is used, leave this pin open.

CLKOUT

Output

This output is the internal system clock signal.

FSEL

Input

Connect this pin to VDD or ground to indicate the frequency

range for the basic clock.

PLLEN

Input

Connect this pin to VDD to enable the built-in phase-looked

loop. If the PLL is not used because an external clock with a

guaranteed duty is available, connect this pin to ground.

VCOM

Input

This input controls the oscillation frequency of the PLL's

voltage-controlled oscillator. Connect it to ground.

System

control

nRST

Input

"L" level input to this pin produces an external system reset for

this LSI. "H" level input then causes execution to resume from

address 0x000000.

DBSEL

Input

During a system reset of this LSI, this input specifies the width

of the external data bus for bank 0. Connect this pin to VDD for

a data bus width of 16bits and to ground for 8bits.

nEA

Input

During a system reset of this LSI, this input controls the use of

the internal ROM. Connect this pin to VDD to enable the ROM

and to ground to disable it.

TEST

Input

During a system reset of this LSI, this input controls the initial

pin functions for the I/O port 8 pins(PIO8[7:0]). Connect this

pin to VDD to initialize the port for its secondary function, the

debugging interface, and to ground for I/O.

Power

Supply

VDD

Input

These pins are this LSI's power supply pins. Connect them all to

VDD.

GND

Input

These pins are this LSI's ground pins. Connect them all to

ground.

AVDD

Input

This pin is the analog-to-digital converter's power supply.

Connect it to VDD.

AGND

Input

This pin is the analog-to-digital converter's

ground pin.

Connect it to ground.
