NAME
FUNCTION
7-0
SBUF.[7:0]
Serial data on the serial port is read from or written to this location. It actually
consists of two separate internal 8-bit registers. One is the receive resister, and
the other is the transmit buffer. Any read access gets data from the receive data
buffer, while write access is to the transmit data buffer.

P2.0
XTAL2 or CLKOUT pin by alternative.
Note:
The initial value of the port is set by CONFIG1.PRHI bit. The default setting for CONFIG1.PRHI =1 which the alternative
function output is turned on upon reset. If CONFIG1.PRHI is set to 0, the user has to write a 1 to port SFR to turn on the
alternative function output.
