Time Slot Bit Selection - HDLC Channel 1
Only bits selected by this register are used for HDLC channel 1 in
selected time slots. Time slot selection is done by setting the
appropriate bits in registers TTR(4:1) and RTR(4:1) independently
for receive and transmit direction. Bit selection is common to receive
and transmit direction. By default all bit positions within the selected
time slot(s) are enabled.
TSB1x = 0 to bit position x in selected time slot(s) is not used for
HDLC channel 1 reception and transmission.
TSB1x = 1 to bit position x in selected time slot(s) is used for HDLC
channel 1 reception and transmission.
Time Slot Bit Selection - HDLC Channel 2
Only bits selected by this register are used for HDLC channel 2 in
selected time slots. Time slot selection is done by setting the
appropriate bits in register TSS2. Bit selection is common to receive
and transmit direction. By default all bit positions within the selected
time slot are enabled.
TSB2x=0 to bit position x in selected time slot(s) is not used for
HDLC channel 2 reception and transmission.
TSB2x=1 to bit position x in selected time slot(s) is used for HDLC
channel 2 reception and transmission.
