UA0BUF is a special function register (SFR) to store the transmit/receive data of the UART.
In transmit mode, write transmission data to UA0BUF. To tranmit data continuously, write the next data to UA0BUF
after making sure that the U0FUL flag of the UART0 status register (UA0STAT) is “0”. Any value written to UA0BUF
can be read.
In receive mode, since data received at termination of reception is stored in UA0BUF, read the contents of UABUF
using the UART0 interrupt at termination of reception. At continuous reception, BA0BUF is updated whenever
reception terminates. Any write to BA0BUF is disabled in receive mode.
The bits not required when 5-bit, 6-bit, 7-bit, or 8-bit data length is slected become invalid in transmit mode and are set
to “0” in receive mode.
Note:
For operation in transmit mode, be sure to set the transmit mode (UA0MOD0 and UA0MOD1) before setting transmit
data in UAOBUF.
