Table 1.6.1 and 1.6.2 describes the available pins.
Pin name Signal name
I/O type
Function
VCC,VSS
Power supply
Apply 0V to the Vss pin, and the following voltage to the Vcc pin.
input
2.7 to 5.5V (Normal-ver.)
3.0 to 5.5V (T-ver.)
4.2 to 5.5V (V-ver.)
CNVSS
Input
Connect this pin to Vss.
____________
RESET
Reset input
Input
"L" on this input resets the microcomputer.
XIN
Clock input
Input
These pins are provided for the main clock generating circuit input/
XOUT
Clock output
Output
output. Connect a ceramic resonator or crystal between the XIN and
the XOUT pins. To use an externally derived clock, input it to the XIN
pin and leave the XOUT pin open. If XIN is not used (for external
oscillator or external clock) connect XIN pin to VCC and leave XOUT
pin open.
AVCC
Analog power
This pin is a power supply input for the A/D converter. Connect this
supply input
pin to VCC.
AVSS
Analog power
This pin is a power supply input for the A/D converter. Connect this
supply input
pin to VSS.
VREF
Reference
Input
This pin is a reference voltage input for the A/D converter.
Voltage input
P00~P07
I/O port P0
Input/output
This is an 8-bit CMOS I/O port. It has an input/output port direction
register that allows the user to set each pin for input or output
individually. When used for input, a pull-up resister option can be
selected for the entire group of four pins.Software can also select
this port to function as A/D converter input pins. P04~P07 are not
available in the 64 pin version.
P10~P17
I/O port P1
Input/output
This is an 8-bit I/O port equivalent to P0. Additional software-select
able secondary functions are: 1) P10 to P13 can act as A/D converter
input pins; 2) P15 to P17 can be configured as external interrupt pins;
3) P15 to P17 can be configured as position-data-retain function
input pins,and; 4) P15 can input a trigger for the A/D converter.
P10~P14 are not available in the 64 pin version.
P20~P27
I/O port P2
Input/output
This is an 8-bit I/O port equivalent to P0. Software can also select
this port to perform as I/O for the Timer S (all pins), and MultiMaster
I2C Bus (P20 and P21 only)
P30~P37
I/O port P3
Input/output
This is an 8-bit I/O port equivalent to P0. P30 to P32 also function as
SIO3 I/O, as selected by software. P34~P37 are not available in the
64 pin version.
P60~P67
I/O port P6
Input/output
This is an 8-bit I/O port equivalent to P0. Pins in this port also func-
tion as UART0 and UART1 I/O, as selected by software.
P70~P77
I/O port P7
Input/output
This is an 8-bit I/O port equivalent to P0. P7 can also function as I/O
for timer A0-A3, as selected by software. Additional programming
options are: P70 to P73 can assume UART1 or UART2 I/O capa-
bilities, and P72 to P75 can function as output pins for the three-
phase motor control timer.
