SBUF0
Serial Data Buffer 0. Data for Serial Port 0 is read from or written to this location. The serial transmit and receive
bits 70
buffers are separate registers, but both are addressed at this location.
SPI Control (SPICON). Any change resets the SPI interface, counters, and pointers. PDCON controls which
is enabled.
