Enables the noise canceler circuit for the corresponding
pin and the pin state is fetched into PBDR at the
sampling cycle set by NCCS.
The operation changes according to the other control
bits. See section 8.1.11 (7), Pin Functions, for details.

Noise Canceler Mode Control Register (P4BNCMC)
P4BNCMC controls whether 1 or 0 is expected for the input signal to port 4 and port B in bit
units.
