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 through which the digital or analog
function, pull-up/pull-down configuration, repeater, and open-drain modes can be
programmed.
The USART, counter/timer, and SSP functions are available on more than one port pin.
Table 4

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 or the USB device
enumeration.
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. A LOW level on this pin during reset starts
the ISP command handler, a HIGH level starts
the USB device enumeration.
USB_VBUS — Monitors the presence of USB
bus power.
