Port 0 is a 32-bit bidirectional I/O port with individual direction controls for each bit.
The operation of port 0 pins depends upon the pin function selected via the Pin
Connect Block. Pins 26 and 31 of port 0 are not available.
TXD0 — Transmitter output for UART0.
PWM1 — Pulse Width Modulator output 1.
RXD0 — Receiver input for UART0.
PWM3 — Pulse Width Modulator output 3.
EINT0 — External interrupt 0 input
SCL — I
CAP0[0] — Capture input for Timer 0, channel 0.
SDA — I
MAT0[0] — Match output for Timer 0, channel 0.
EINT1 — External interrupt 1 input.
SCK0 — Serial clock for SPI0. SPI clock output from master or input to slave.
CAP0[1] — Capture input for Timer 0, channel 1.
MISO0 — Master In Slave OUT for SPI0. Data input to SPI master or data output
from SPI slave.
MAT0[1] — Match output for Timer 0, channel 1.
MOSI0 — Master Out Slave In for SPI0. Data output from SPI master or data input
to SPI slave.
CAP0[2] — Capture input for Timer 0, channel 2.
SSEL0 — Slave Select for SPI0. Selects the SPI interface as a slave.
PWM2 — Pulse Width Modulator output 2.
EINT2 — External interrupt 2 input.
TXD1 — Transmitter output for UART1.
PWM4 — Pulse Width Modulator output 4.
RXD1 — Receiver input for UART1.
PWM6 — Pulse Width Modulator output 6.
EINT3 — External interrupt 3 input.
RTS1 — Request to Send output for UART1.
CAP1[0] — Capture input for Timer 1, channel 0.
CTS1 — Clear to Send input for UART1.
CAP1[1] — Capture input for Timer 1, channel 1.
DSR1 — Data Set Ready input for UART1.
MAT1[0] — Match output for Timer 1, channel 0.
DTR1 — Data Terminal Ready output for UART1.
MAT1[1] — Match output for Timer 1, channel 1.
DCD1 — Data Carrier Detect input for UART1.
EINT1 — External interrupt 1 input.
Note: LOW on this pin while RESET is LOW forces on-chip bootloader to take
control of the part after reset.
