2.8.2 Other Input Signals
As shown in the table below, about input signals other than nPIOm signals, when the functions of those signals are not used, they
can be used as a general purpose input signal.
The signal levels of input signals are displayed in RR3 register Page0. When the signal is Low level, 0 is displayed and when the
signal is Hi level, 1 is displayed.
Input signals that can be used as a general purpose input signal are shown in the table below.
