Noise Filter Control Register
When MSEL =
provides control for the digital noise filter.
Table 91. Noise Filter Control Register (U0CTL1 = F43H with MSEL = 001b)
Noise Filter Enable (NFEN)—See the bit descriptions in
Noise Filter Control (NFCTL)—This field controls the delay and noise rejection charac-
teristics of the noise filter. The wider the counter is, the more delay is introduced by the 
filter, and the wider the noise event is filtered.
