Description
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.
I_HIGHGAIN — High gain current input for metrology
engine.
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. Pins
PIO1_0 and PIO1_10 are not available.
VOLTAGE — Voltage input for the metrology engine.
R — Reserved. Configure for an alternate function in
the IOCONFIG block.
PIO1_1 — General purpose digital input/output pin.
CT32B1_MAT0 — Match output 0 for 32-bit timer 1.
R — Reserved. Configure for an alternate function in
the IOCONFIG block.
PIO1_2 — General purpose digital input/output pin.
CT32B1_MAT1 — Match output 1 for 32-bit timer 1.
SWDIO — Serial wire debug input/output.
PIO1_3 — General purpose digital input/output pin.
CT32B1_MAT2 — Match output 2 for 32-bit timer 1.
PIO1_4 — General purpose digital input/output pin.
CT32B1_MAT3 — Match output 3 for 32-bit timer 1.
WAKEUP — Deep power-down mode wake-up pin with
20 ns glitch filter. This pin must be pulled HIGH
externally to enter Deep power-down mode and pulled
LOW to exit Deep power-down mode. A LOW-going
pulse as short as 50 ns wakes up the part.
PIO1_5 — General purpose digital input/output pin.
RTS — Request To Send output for UART.
CT32B0_CAP0 — Capture input 0 for 32-bit timer 0.
PIO1_6 — General purpose digital input/output pin.
RXD — Receiver input for UART.
CT32B0_MAT0 — Match output 0 for 32-bit timer 0.
PIO1_7 — General purpose digital input/output pin.
TXD — Transmitter output for UART.
CT32B0_MAT1 — Match output 1 for 32-bit timer 0.
PIO1_8 — General purpose digital input/output pin.
PIO1_9 — General purpose digital input/output pin.
I_LOWGAIN — Low gain current input for metrology
engine.
