C2 clock input/output (this pin does not
use a specialized I2C pad).
O T3_MAT3 — Match output for Timer 3, channel 3.
P3[0] to P3[31] I/O Port 3: Port 3 is a 32-bit I/O port with individual direction
controls for each bit. The operation of port 3 pins depends
upon the pin function selected via the pin connect block.
