• U0FUL (bit 3)
The U0FUL bit is used to indicate the state of the transmit/receive buffer of the UART.
When transmit data is written in UA0BUF in transmit mode, this bit is set to “1” and when transmit data is
transferred to the shift register, this bit is set to “0”. To transmit data consecutively, write the next transmit data to
UA0BUF after checking that the U0FUL flag has been set to “0”.
The U0FUL bit is fixed to “0” in receive mode.
