Chapter 12 Synchronous Serial Port
12.2.3 Serial Port 1 Transmit/Receive Buffers (SIO1BUFL and SIO1BUFH)
Address: 0F288H
Access: R/W
Access size: 8 bits/16 bits
Initial value: 00H
Address: 0F289H
Access: R/W
Access size: 8-bit
Initial value: 00H
SIO1BUFL and SIO1BUFH are special function registers (SFRs) to write transmitted data and to read received data of
the synchronous serial port 1.
When data is written in SIO1BUFL and SIO1BUFH, the data is written in the transmit registers (SIO1TRL and
SIO1TRH). When data is read from SIO1BUFL and SIO1BUFH, the contents of the receive registers (SIO1RCL and
SIO1RCH) are read.
