SIO0BUFL and SIO0BUFH are special function registers (SFRs) to write transmit data and to read receive data of the
synchronous serial port.
When data is written in SIO0BUFL and SIO0BUFH, the data is written in the transmit registers (SIO0TRL and
SIO0TRH) and when data is read from SIO0BUFL and SIO0BUFH, the contents of the receive registers (SIO0RCL
and SIO0RCH) are read.
