Description
Transmit FIFO Data Count Trigger
These bits are used to set the number of remaining
transmit data bytes that sets the TDFE flag in SCFSR.
The TDFE flag is set when the number of transmit data
bytes in SCFTDR is equal to or less than the trigger
setting count shown below.
00: 32 (32)*
01:16 (48)
10: 2 (62)
11: 0 (64)
Modem Control Enable
Enables the SCIF_CTS and SCIF_RTS modem control
signals. Always set the MCE bit to 0 in clocked
synchronous mode.
0: Modem signals disabled*
1: Modem signals enabled
Transmit FIFO Data Count Register Clear
Clears the transmit data count in the transmit FIFO
data count register to 0.
0: The FIFO data count not cleared*
1: The FIFO data count cleared to 0
Receive FIFO Data Count Register Clear
Clears the receive data count in the receive FIFO data
count register to 0.
0: The FIFO data count not cleared*
1: The FIFO data count cleared
Loopback Test
Internally connects the transmit output pin (SCIF_TXD)
and receive input pin (SCIF_RXD), and the SCIF_RTS
pin and SCIF_CTS pin, enabling loopback testing.
0: Loopback test disabled
1: Loopback test enabled
