Description
PIO0_0 to PIO0_10
I/O
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/PIO0_0
yes
I
I;PU
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.
I/O
-
PIO0_0 — General purpose digital input/output pin.
PIO0_1/CLKOUT/
CT32B0_MAT2
yes
I/O
I;PU
PIO0_1 — General purpose digital input/output pin. A
LOW level on this pin during reset starts the ISP
command handler.
O-
CLKOUT — Clock out pin.
O-
CT32B0_MAT2 — Match output 2 for 32-bit timer 0.
PIO0_2/SSEL0/
CT16B0_CAP0
yes
I/O
I;PU
PIO0_2 — General purpose digital input/output pin.
I/O
-
SSEL0 — Slave select for SPI0.
I-
CT16B0_CAP0 — Capture input 0 for 16-bit timer 0.
PIO0_3
yes
I/O
I;PU
PIO0_3 — General purpose digital input/output pin.
PIO0_4/SCL
yes
I/O
IA
PIO0_4 — General purpose digital input/output pin
(open-drain).
I/O
-
SCL — I2C-bus, open-drain clock input/output.
High-current sink only if I2C Fast-mode Plus is selected
in the I/O configuration register.
PIO0_5/SDA
yes
I/O
IA
PIO0_5 — General purpose digital input/output pin
(open-drain).
I/O
-
SDA — I2C-bus, open-drain data input/output.
High-current sink only if I2C Fast-mode Plus is selected
in the I/O configuration register.
PIO0_6/SCK0
yes
I/O
I;PU
PIO0_6 — General purpose digital input/output pin.
I/O
-
SCK0 — Serial clock for SPI0.
PIO0_7/CTS
yes
I/O
I;PU
PIO0_7 — General purpose digital input/output pin
(high-current output driver).
I-
CTS — Clear To Send input for UART.
PIO0_8/MISO0/
CT16B0_MAT0
yes
I/O
I;PU
PIO0_8 — General purpose digital input/output pin.
I/O
-
MISO0 — Master In Slave Out for SPI0.
O-
CT16B0_MAT0 — Match output 0 for 16-bit timer 0.
PIO0_9/MOSI0/
CT16B0_MAT1
yes
I/O
I;PU
PIO0_9 — General purpose digital input/output pin.
I/O
-
MOSI0 — Master Out Slave In for SPI0.
