x = unknown, - = unimplemented locations read as ‘0’. Shaded cells are not used for asynchronous reception.
Bits PSPIE and PSPIF are reserved on 28-pin devices; always maintain these bits clear.
This timing diagram shows a data byte followed by an address byte. The data byte is not read into the RCREG (Receive Buffer)
because ADDEN was not updated and still = 0.
