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 applied to this pin.
These are input and output pins of the internal clock generating circuit. Connect a
ceramic or quartz-crystal oscillator between the XIN and XOUT pins. When an
external clock is used, the clock source should be connected to the XIN pin, and the
XOUT pin 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 converter and the D-A converter. Connect AVcc
to Vcc, and AVss to Vss externally.
This is the reference voltage input pin for the A-D converter and the D-A converter.
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
at reset. These pins also function as I/O port pins of UART0 and UART1.
In addition to having the same functions as port P1, these pins also function as I/O
pins for timers A4 and A9. By software setting, these pins also function as input
pins for timers B0–B2, an input pin for INT3, and a trigger input pin in the pulse
output port mode.
In addition to having the same functions as port P1, these pins also function as
input pins for INT5–INT7, input pins for timers B0–B2, and input pins for position-
data-input pins in the three-phase waveform mode.
In addition to having the same functions as port P1, these pins also function as I/O
pins for timers A0–A2, and output pins for the motor drive waveform.
In addition to having the same functions as port P1, these pins also function as
input pins for the A-D converter. P73 functions as an output pin for the D-A
converter; P74 functions as an output pin for the D-A converter, an input pin for
INT3, and a trigger input pin in the pulse output port mode.
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.
