number. The default function after reset is listed first. All port pins have internal pull-up
resistors enabled after reset with the exception of the true open-drain pins PIO0_4 and
PIO0_5.
Every port pin has a corresponding IOCON register for programming the digital or analog
function, the pull-up/pull-down configuration, the repeater, and the open-drain modes.
The USART, counter/timer, and SSP functions are available on more than one port pin.
Table 4
shows all pins and their assigned digital or analog functions ordered by GPIO port
shows how peripheral functions are assigned to port pins.

Description
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. This
pin also serves as the debug select input. LOW
level selects the JTAG boundary scan. HIGH
level selects the ARM SWD debug mode.
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 — Clockout pin.
CT32B0_MAT2 — Match output 2 for 32-bit
timer 0.
USB_FTOGGLE — USB 1 ms Start-of-Frame
signal.
PIO0_2 — General purpose digital input/output
pin.
SSEL0 — Slave select for SSP0.
CT16B0_CAP0 — Capture input 0 for 16-bit
timer 0.
PIO0_3 — General purpose digital input/output
pin.
USB_VBUS — Monitors the presence of USB
bus power.
PIO0_4 — General purpose digital input/output
pin (open-drain).
SCL — I
High-current sink only if I
selected in the I/O configuration register.
