U0FUL
(bit 3)
The U0FUL bit is used to indicate the state of the transmit/receive buffer of the UART.
When the transmitted data is written in UA0BUF in transmit mode, this bit is set to “1” and when this transmitted
data is transferred to the shift register, this bit is set to “0”. To transmit the data consecutively, confirm the
U0FUL flag becomes "0", then write the next transmitted data to the UA0BUF.
The U0FUL bit is fixed to “0” in receive mode.
U0FUL
Description
0
There is no data in the transmit/receive buffer. (Initial value)
