I
I;PU
SWCLK — Serial wire clock.
I/O
-
PIO0_10 — General purpose digital input/output pin.
I/O
-
SCK0 — Serial clock for SPI0.
O-
CT16B0_MAT2 — Match output 2 for 16-bit timer 0.
I_HIGHGAIN
no
I
I;PU
I_HIGHGAIN — High gain current input for metrology
engine.
PIO1_1 to PIO1_9;
PIO1_11
I/O
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
no
I
I;PU
VOLTAGE — Voltage input for the metrology engine.
R/PIO1_1/
CT32B1_MAT0
no
O
I;PU
R — Reserved. Configure for an alternate function in
the IOCONFIG block.
