Pin Functions
1.7.9 Port C I/O Pins (PC7–PC0)
These eight I/O pins comprise port C, a general-purpose, bidirectional
I/O port. The pins are programmable as either inputs or outputs under
software control of the data direction registers. PC7 has a high current
sink and source capability. See 7.5 Port C.
1.7.10 Port D I/O Pins (PD7 and PD5–PD0)
These seven lines comprise port D, a fixed input port. All special
functions that are enabled (SPI and SCI) affect this port. See 7.6 Port D.
NOTE: Connecting the V_PP pin (programming voltage) to V_SS (ground) could
result in damage to the MCU.
