TX Complete
0 = Indicates that if a transmission has been initiated, it is still in progress
1 = Indicates that the current transmission is complete (including framing bits)
Optional interrupt source for TX UART. Reset when this register is read.
Bit 4
:
TX Reg Empty
0 = Indicates TX Data register is not available to accept another byte (writing to register will cause data to be lost)
1 = Indicates TX Data register is available to accept another byte
Note that the interrupt does not occur until at least 1 byte has been previously written to the TX Data Register
Default interrupt source for TX UART. Reset when the TX Data Register (Data Register 1) is written.
