Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Bits 12 to 8 in SCFDR show the number of
untransmitted data bytes in SCFTDR.
A value of H'00 means that there is no transmit data,
and a value of 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.
Bits 4 to 0 in SCFDR show the number of receive
data bytes in SCFRDR.
A value of H'00 means that there is no receive data,
and a value of H'10 means that SCFRDR is full of
receive data.
