SPBRG Baud Rate Generator register
Legend: u= unchanged, x= unknown, - = unimplemented, read as '0'.
Shaded cells are not used for synchronous slave transmission.
Note 1: Bits PSPIE and PSPIF are reserved on the PIC16C63A/73B; always maintain these bits clear.
2: Bits ADIE and ADIF are reserved on the PIC16C63A/65B; always maintain these bits clear.
