TXD — Transmitter output for UART.
CT32B0_MAT1 — Match output 1 for 32-bit timer 0.
PIO1_8 — General purpose digital input/output pin.
CT16B1_CAP0 — Capture input 0 for 16-bit timer 1.
PIO1_9 — General purpose digital input/output pin.
CT16B1_MAT0 — Match output 0 for 16-bit timer 1.
PIO1_10 — General purpose digital input/output pin.
AD6 — A/D converter, input 6.
CT16B1_MAT1 — Match output 1 for 16-bit timer 1.
PIO1_11 — General purpose digital input/output pin.
AD7 — A/D converter, input 7.
Port 2 — Port 2 is a 12-bit I/O port with individual direction and function
controls for each bit. The operation of port 2 pins depends on the function
selected through the IOCONFIG register block.
