Receive LAPD Control
These bits select which one of the three Receive LAPD controller will be con-
figured to use D/E time slot (Octets 0-23) for receiving LAPD messages.
N
OTE
:
All three LAPD Controller can use D/E timeslots for receiving LAPD
messages. However, only LAPD Controller 1 can use datalink for
reception.
N
OTE
:
Register 0xn360 represents D/E time slot 0, and 0xn37F represents
D/E time slot 31.
