13.2.2 UART0 Transmit/Receive Buffer (UA0BUF)
Address: 0F290H
Access: R/W
Access size: 8-bit
Initial value: 00H
UA0BUF is a special function register (SFR) to store the transmitted/received data of the UART.
In transmit mode, write transmission data to UA0BUF. To transmit the data consecutively, confirm the U0FUL flag of
the UART0 status register (UA0STAT) becomes "0", then write the next transmitted data to the UA0BUF. 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, which are not required when any of the 5- to 8-bit data length is selected, become invalid in transmit mode and
are set to “0” in receive mode.
Note:
Initial value
UA0BUF
For operation in transmit mode, be sure to set the transmit mode (UA0MOD0 and UA0MOD1) before setting the
transmitted data in UAOBUF.
