- = Unimplemented, u = Unchanged. 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 PIC18F2X31 devices; maintain these bits clear. Reset values shown are for PIC18F4X31 devices.
