(21) Comparator output digital noise elimination register nL, nF (CMPNFCnL, CMPNFCnF)
Note When using the comparator output, be sure to set the CMPnNFEN bit to 1 (digital noise eliminated). At
Caution Be sure to set bits 3 to 6 to “0”.
The CMPNFCnL and CMPNFCnF registers are control the digital noise elimination of the overvoltage detection
comparator output.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.
the same time, a sampling clock must be selected.
When not using the comparator output, set the CMPnNFEN bit to 0.
