1.5 Pin Description

Apply 0V to the Vss pin. Apply following voltage to the Vcc pin.

2.7 to 5.5 V (Normal), 3.0 to 5.5 V (T-ver.), 4.2 to 5.5 V (V-ver.)

Supplies power to the A/D converter. Connect the AVCC pin to VCC and

the AVSS pin to VSS

___________

The microcomputer is in a reset state when "L" is applied to the RESET pin

Connect the CNVSS pin to VSS

I/O pins for the main clock oscillation circuit. Connect a ceramic resonator

or crystal oscillator between XIN and XOUT. To apply external clock, apply

it to XIN and leave XOUT open. If XIN is not used (for external oscillator or

external clock) connect XIN pin to VCC and leave XOUT open

I/O pins for the sub clock oscillation circuit. Connect a crystal oscillator

between XCIN and XCOUT

Outputs the clock having the same frequency as f1, f8, f32, or fC

______

________

Input pins for the INT interrupt. INT2 can be used for Timer A Z-phase

function

_______

Input pin for the NMI interrupt. NMI cannot be used as I/O port while the three-

_______

phase motor control is enabled. Apply a stable "H" to NMI after setting it's

direction register to "0" when the three-phase motor control is enabled
