(3) Mode 7
In mode 7, port C pins function as PWM outputs and I/O ports and I/O can be specified for each
pin in bit units. When each bit in PCDDR is set to 1, the corresponding pin functions as an output
port and when the bit is cleared to 0, the pin functions as an input port.
Figure 10A-15 shows the port C pin functions.
