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. Pin
PIO0_11 is not available.
RESET — External reset input with 20 ns glitch filter. A
LOW-going pulse as short as 50 ns 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
High-current sink only if I
in the I/O configuration register.
PIO0_5 — General purpose digital input/output pin
(open-drain).
SDA — I
High-current sink only if I
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.
