RDC1.7
Receive HDLC source
0 = Sa bits defined by RCR2.3 to RCR2.7.
1 = Sa bits or DS0 channels defined by RDC1 (see bits defined
below).
RSaDS
RDC1.6
Receive Sa Bit / DS0 Select.
0 = route Sa bits to the HDLC controller. RD0 to RD4 defines
which Sa bits are to be routed. RD4 corresponds to Sa4, RD3
to Sa5, RD2 to Sa6, RD1 to Sa7 and RD0 to Sa8.
1 = route DS0 channels into the HDLC controller. RDC1.5 is
used to determine how the DS0 channels are selected.
RDS0M
RDC1.5
DS0 Selection Mode.
0 = utilize the RD0 to RD4 bits to select which single DS0
channel to use.
1 = utilize the RCHBLK control registers to select which DS0
channels to use. This option is not applicable for the
DS21FT40.
RD4
RDC1.4
DS0 Channel Select Bit 4. MSB of the DS0 channel select.
RD3
RDC1.3
DS0 Channel Select Bit 3.
RD2
RDC1.2
DS0 Channel Select Bit 2.
RD1
RDC1.1
DS0 Channel Select Bit 1.
RD0
RDC1.0
DS0 Channel Select Bit 0. LSB of the DS0 channel select.
