— = Unimplemented, read as ‘0’. Shaded cells are not used with the power control PWM.
Double-buffered register pairs. Refer to text for explanation of how these registers are read and written to.
Unimplemented in PIC18F2331/2431 devices; maintain these bits clear. Reset values shown are for
PIC18F4331/4431 devices.
