UART Transmit Interrupt FIFO Level Select
The trigger points for the transmit interrupt are as follows:
DescriptionValue
TX FIFO ≤ ⅞ empty0x0
TX FIFO ≤ ¾ empty0x1
TX FIFO ≤ ½ empty (default)0x2
TX FIFO ≤ ¼ empty0x3
TX FIFO ≤ ⅛ empty0x4
Reserved0x5-0x7
Note: If the EOT bit in UARTCTL is set (see page 1188), the transmit
interrupt is generated once the FIFO is completely empty and
all data including stop bits have left the transmit serializer. In
this case, the setting of TXIFLSEL is ignored.
