Transmit HDLC Frame Select.
These bits are encoded to select odd and/or even num-
bered frames assigned to this channel.
00 = No data selected.
01 = Data to even frames selected (F
10 = Data to odd frames selected (F
11 = Data to all (even and odd) frames selected.
Reserved. Must write to 0.
Transmit HDLC Link Select.
These bits indicate (in binary) the link number assigned to
this channel.
Reserved. Must write to 0.
These bits indicate (in binary) the time slot number
assigned to this channel.
Transmit HDLC Bit Assignment.
These bits indicate which bits of a time slot are to be
assigned to this channel (1 = bit assigned).
In loopback mode, set as follows:
00000000 = slowest (~6 kbits/s at 52MHz)
10000000 = faster (~2x above)
11000000 = faster still (~4x slowest rate)
. . . .
11111111 = fastest (~1.5 Mbits/s at 52MHz)
Note: If running a mix of loopback and nonloopback
8
channels, the loopback speed should not be set
faster than 11100000.
