Description
SWCLK — Serial wire clock, default location.
ACMP1_I3 — Input 3 for comparator 1.
CT32B1_CAP3 — Capture input, channel 3 or 32-bit timer 1.
CT32B1_MAT3 — Match output, channel 3 for 32-bit timer 1.
PIO0_26 — General purpose digital input/output pin.
PIO0_27 — General purpose digital input/output pin
(high-current output driver).
ACMP0_O — Output for comparator 0.
PIO0_28 — General purpose digital input/output pin
(high-current output driver).
ACMP1_O — Output for comparator 1.
CT16B0_CAP0 — Capture input, channel 0 for 16-bit timer 0.
CT16B0_MAT0 — Match output, channel 0 for 16-bit timer 0.
PIO0_29 — General purpose digital input/output pin
(high-current output driver).
ROSC — Relaxation oscillator for 555 timer applications.
CT16B0_CAP1 — Capture input, channel 1 for 16-bit timer 0.
CT16B0_MAT1 — Match output, channel 1 for 16-bit timer 0.
R — Reserved. Configure for an alternate function in the
IOCONFIG block.
PIO0_30 — General purpose digital input/output pin.
AD0 — A/D converter, input 0.
R — Reserved. Configure for an alternate function in the
IOCONFIG block.
PIO0_31 — General purpose digital input/output pin.
AD1 — A/D converter, input 1.
Port 1 — Port 1 is a 32-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_7 through PIO1_31 are not available.
R — Reserved. Configure for an alternate function in the
IOCONFIG block.
PIO1_0 — General purpose digital input/output pin.
AD2 — A/D converter, input 2.
R — Reserved. Configure for an alternate function in the
IOCONFIG block.
PIO1_1 — General purpose digital input/output pin.
AD3 — A/D converter, input 3.
PIO1_2 — General purpose digital input/output pin.
SWDIO — Serial wire debug input/output, alternate location.
AD4 — A/D converter, input 4.
