Legend: x= unknown, u= unchanged, - = unimplemented, read as '0'.
Shaded cells are not used by Capture and Compare, Timer1 or Timer3.
Note 1: Generic term for all of the identical registers of this name for all CCP modules, where ‘x’ identifies the individual module
(CCP1 through CCP5). Bit assignments and RESET values for all registers of the same generic name are identical.
