When DDRBx is a logic 1, reading address $0001 reads the PTBx data latch. When DDRBx is a logic 0,
reading address $0001 reads the voltage level on the pin. The data latch can always be written,
regardless of the state of its data direction bit.

16.4 Port C
Port C is an 8-bit special-function port that shares one of its pins with the IRQ2, four of its pins with the
SPI module, and two of its pins with the IRSCI module.
16.4.1 Port C Data Register (PTC)
The port C data register contains a data latch for each of the eight port C pins.

Alternative Function:
summarizes the operation of the port B pins.
1. X = don’t care.
2. Hi-Z = high impedance.
3. Writing affects data register, but does not affect input.
