15.3.10 FIFO Data Count Set Register (SCFDR)
SCFDR is a 16-bit register which indicates the quantity of data stored in the transmit FIFO data
register (SCFTDR) and the receive FIFO data register (SCFRDR).
It indicates the quantity of transmit data in SCFTDR with the upper 8 bits, and the quantity of
receive data in SCFRDR with the lower 8 bits. SCFDR can always be read by the CPU.

Description
Loop-Back Test
Internally connects the transmit output pin (TxD) and
receive input pin (RxD) and internally connects the RTS
pin and CTS pin and enables loop-back testing.
0: Loop back test disabled
1: Loop back test enabled
Description
Reserved
These bits are always read as 0. The write value should
always be 0.
T4 to T0 bits indicate the quantity of non-transmitted
data stored in SCFTDR. H'00 means no transmit data,
and H'10 means that SCFTDR is full of transmit data.
Reserved
These bits are always read as 0. The write value should
always be 0.
R4 to R0 bits indicate the quantity of receive data
stored in SCFRDR. H'00 means no receive data, and
H'10 means that SCFRDR full of receive data.
