Bits PSPIE and PSPIF are reserved on the PIC16C73/73A/76, always maintain these bits clear.
The PIC16C72 does not have a Parallel Slave Port or a USART, these bits are unimplemented, read as '0'.
x = unknown, u = unchanged, - = unimplemented read as '0'. Shaded cells are not used by the Timer2 module.
