Pin Functions (64-Pin and 80-Pin Packages)
Signal Name
Pin Name
I/O
Description
Power supply
VCC, VSS
I
Apply 3.0 V to 5.5 V to VCC pin and 0 V to VSS pin.
Analog power
supply
AVCC,
AVSS
I
Power supply for the A/D converter. AVCC and AVSS should be
connected to VCC and VSS, respectively.
Reset input
RESET
I
Low active input pin. Driving this low resets the MCU.
CNVSS
I
Connect the CNVSS to VSS.
Main clock input
XIN
I
Input/output pin for the main clock oscillator. Connect a ceramic
resonator or crystal oscillator between XIN and XOUT. To apply an
external clock, connect it to XIN and leave XOUT open. When XIN is
not used, connect XIN to VCC pin and leave XOUT open.
Main clock output
XOUT
O
Sub clock input
XCIN
I
Input/output for the sub clock oscillator. Connect a crystal oscillator
between XCIN and XCOUT.
Sub clock output
XCOUT
O
Clock output
CLKOUT
O
This pin outputs the clock having the same frequency as f1, f8, f32,
or fC.
INT interrupt input
INT0 to INT5
I
Low active input pins for
INT interrupt. INT2 is used to input Z-phase
of timer A.
NMI input
NMI
I
Low active input pin for
NMI interrupt. NMI cannot be used as I/O
port while the three-phase motor control is enabled. Apply a stable
high to
NMI after setting its direction register to 0 when the three-
phase motor control is enabled.
Key input interrupt
KI0 to KI3
I
Low active Input pins for the key input interrupt
Timer A
TA0OUT to
TA4OUT
I/O
Timers A0 to A4 input/output pins
TA0IN to TA4IN
I
Timers A0 to A4 input pins
ZP
I
Input pin for Z-phase
Timer B
TB0IN to TB2IN
I
Timers B0 to B2 input pins
Three-phase motor
control timer output
U,
U,V,V,W,W
O
Output pins for three-phase motor control timer
IDU, IDW, IDV,
SD
I/O
Input/output pins for three-phase motor control timer
Real time clock
RTCOUT
O
Output pin for real time clock
Serial interface
CTS0 to CTS3
I
Input pins to control data transmission
RTS0 to RTS3
O
Output pins to control data reception
CLK0 to CLK3
I/O
Transfer clock input/output pins
RXD0 to RXD3
I
Serial data input pins
TXD0 to TXD3
O
Serial data output pins
I2C mode
SDA2
I/O
Serial data input/output pin
SCL2
I/O
Transfer clock input/output pin
Multi-master I2C
bus
SDAMM
I/O
Serial data input/output pin
SCLMM
Transfer clock input/output pin
