Port 1
is a combination of 5 bits of push-pull bidirectional I/
O ports and 3 bits of input ports.
As alternate digital functions, port 1 contains the
interrupt 3, timer 2 overflow flag, receive data input
and transmit data output of serial interface. The
alternate functions are assigned to the pins of port
1 as follows:
P1.0/TxD Transmit data of serial interface
P1.1/EXF2 Timer 2 overflow flag
P1.2
P1.3/INT3 Interrupt 3
P1.4/RxD Receive data of serial interface, Use as
wakeup source from powerdown if bit WS of
PMCON0 is set.
The input ports are also interrupt ports, input to the
timer2, CCU6 modules and ADC:
P1.5/Input to Counter 2/External Interrupt 0 Input/
Analog Input Channel 0
External interrupt input or Hall input signal, counter
2 input or input channel 0 to the ADC unit. Use as
wakeup source from powerdown if bit WS of
PMCON0 is cleared.
P1.6/Timer 2 Trigger/External Interrupt 1 Input/
Analog Input Channel 1
External interrupt input or Hall input signal, input
channel 1 to the ADC unit, trigger to Timer 2.
P1.7/External Interrupt 2 Input/
Analog Input Channel 2
External interrupt input or Hall input signal and input
channel 2 to the ADC unit.
