Description
Port 0 — Port 0 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 0 pins depends on the function
selected through the IOCONFIG register block.
RESET — External reset input: A LOW on this pin resets the device,
causing I/O ports and peripherals to take on their default states, and
processor execution to begin at address 0.
PIO0_0 — General purpose digital input/output pin.
PIO0_1 — General purpose digital input/output pin. A LOW level on this pin
during reset starts the ISP command handler.
CLKOUT — Clock out pin.
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
PIO0_2 — General purpose digital input/output pin.
SSEL0 — Slave select for SPI0.
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3 — General purpose digital input/output pin.
PIO0_4 — General purpose digital input/output pin (open-drain).
SCL — I
Fast-mode Plus is selected in the I/O configuration register.
PIO0_5 — General purpose digital input/output pin (open-drain).
SDA — I
Fast-mode Plus is selected in the I/O configuration register.
PIO0_6 — General purpose digital input/output pin.
SCK0 — Serial clock for SPI0.
PIO0_7 — General purpose digital input/output pin (high-current output
driver).
CTS — Clear To Send input for UART.
PIO0_8 — General purpose digital input/output pin.
MISO0 — Master In Slave Out for SPI0.
CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
PIO0_9 — General purpose digital input/output pin.
MOSI0 — Master Out Slave In for SPI0.
CT16B0_MAT1 — Match output 1 for 16-bit timer 0.
SWCLK — Serial wire clock.
PIO0_10 — General purpose digital input/output pin.
SCK0 — Serial clock for SPI0.
CT16B0_MAT2 — Match output 2 for 16-bit timer 0.
R — Reserved. Configure for an alternate function in the IOCONFIG block.
PIO0_11 — General purpose digital input/output pin.
AD0 — A/D converter, input 0.
CT32B0_MAT3 — Match output 3 for 32-bit timer 0.
Port 1 — Port 1 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 1 pins depends on the function
selected through the IOCONFIG register block.
