Functions

Apply 5 V±0.5 V to Vcc, and 0 V to Vss.

Connect this pin to VSS.

Connect this pin to Vss.

The microcomputer is reset when “L” level is applies to this pin.

These are input and output pins of the internal clock generating circuit. Connect a

ceramic resonator or quartz-crystal oscillator between pins XIN and XOUT. When an

external clock is used, the clock source should be connected to pin XIN, and pin

XOUT should be left open.

When using the PLL frequency multiplier, connect this pin to the filter circuit. When

not using the PLL frequency multiplier, this pin should be left open.

Power supply input pins for the A-D and D-A converters. Connect AVcc to Vcc, and

AVss to Vss externally.

This is the reference voltage input pin for the A-D and D-A converters.

Port P1 is an 8-bit I/O port. This port has an I/O direction register, and each pin can

be programmed for input or output. These pins enter the input mode ar reset. These

pins also function as I/O pins of UART0, 1.

In addition to having the same functions as port P1, these pins function as I/O pins

for timers A4 and A9. Also, they can be programmed to function as input pins for tim-

ers B0 to B2.

In addition to having the same functions as port P1, these pins function as I/O pins

for timers A5 to A8. Also, they function as output pins for motor drive waveform.

In addition to having the same functions as port P1, these pins function as input pins

for INT1 to INT3 and INT5 to INT7. Also, pins P55 to P57 function as input pins for

timers B0 to B2 and as input pins for position data in the three-phase waveform

mode; and pins P52 and P53 function as trigger-input pins in the pulse output port

mode.

In addition to having the same functions as port P1, these pins function as I/O pins

for timers A0 to A3. Also, they function as motor drive waveform output pins.

In addition to having the same functions as port P1, these pins function as input pins

for the A-D converter. Also, P77 functions as an output pin for the D-A converter.

In addition to having the same functions as port P1, these pins function as input pins

for the A-D converter. Also, these pins function as I/O pins for UART2,and pin P80

functions as an output pin for the D-A converter.

This pin has the function to forcibly place port P4 pins in the input mode. Also, this

pin functions as an input pin for INT0; and this pin is used to input a signal, which

forcibly cuts off a motor drive waveform output.

This pin has the function to forcibly place port P6 pins in the input mode. Also, this

pin functions as an input pin for INT4; and this pin is used to input a signal, which

forcibly cuts off a motor drive waveform output.
