20.14 SC Port
The SC port is an 8-bit input/output port with the pin configuration shown in figure 20.14. Each
pin has an input pull-up MOS, which is controlled by the SC port control register (SCPCR) in the
PFC.

Note: * SCPT0 and SCPT2 each have two separate pins for input
and output, however, a common data register is accessed.
