5. PIN DESCRIPTION
PIN
Name
I/O Function @RESET Shared with
P00 I/O - 8-bit I/O port, P0.
- Can be set in input or output mode bitwise.
- Internal pull-up resistor can be activated by
setting PxnPU bit in PxPU register when this
port is used as input port.
- Can be configured as an open drain output
mode by setting PxnOD bit in PxOD register.
Input KS0/T0
P01 KS1/T1/PWM1
P02 KS2/T2
P03 KS3/T3/PWM3
P04 KS4/EC0
P05 KS5
P06 KS6
P07 KS7
P10 I/O 8-bit I/O port, P1.
- Can be set in input or output mode bitwise.
- Internal pull-up resistor can be activated by
setting PxnPU bit in PxPU register when this
port is used as input port.
- Can be configured as an open drain output
mode by setting PxnOD bit in PxOD register.

P20 I/O - 3-bit I/O port, P2.
- Can be set in input or output mode bitwise.
- Internal pull-up resistor can be activated by
setting PxnPU bit in PxPU register when this
port is used as input port.
- Can be configured as an open drain output
mode by setting PxnOD bit in PxOD register.
Input RESETB NOTE1
P21 INT2/DSCL/
SCL NOTE2
P22 INT3/DSDA/
SDA NOTE2
- - -
NOTE0 INT3,2,1,0 can be triggered on P2[2:1], P3[7:6] ports when appropriate bits in PSR0 register are set.
NOTE1
When P20 is used as a external reset pin(=RESETB) by the FUSE configuration, this pin is configured as
an input port with internal pull-up resistor on.
NOTE2
SDA and SCL ports can be switched to P3[7:6] ports when appropriate bits in PSR0 register are set.
