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

.
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 X
IN
and X
OUT
. When an
external clock is used, the clock source should be connected to pin X
IN
, and pin
X
OUT
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 INT
1
to INT
3
and INT
5
to INT
7
. Also, pins P5
5
to P5
7
function as input pins for tim-
ers B0 to B2 and as input pins for position data in the three-phase waveform mode;
and pins P5
2
and P5
3
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, P7
7
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 P8
0
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 INT
0
; 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 INT
4
; and this pin is used to input a signal, which
forcibly cuts off a motor drive waveform output.
