Description
Noise cancel circuit is enabled when P6NCE bit is
set to 1, and the pin state is fetched in the P6DR in
the sampling cycle set by the P6NCCS.
Description
1 expected: 1 is stored in the port data register
when 1 is input stably
0 expected: 0 is stored in the port data register
when 0 is input stably
