INT0
Bit 2
External Interrupt 0. A falling edge/low level on this pin will cause an external
interrupt 0 if enabled.
TXD0
Bit 1 Serial Port 0 Transmit. This pin transmits the serial port 0 data in serial port
modes 1, 2, 3 and emits the synchronizing clock in serial port mode 0.
RXD0
Bit 0 Serial Port 0 Receive. This pin receives the serial port 0 data in serial port modes
1, 2, 3 and is a bidirectional data transfer pin in serial port mode 0.
