basis or on a global basis of the corresponding link (the methods are
arranged from the highest to the lowest in priority):
by specifying the address in the ADDRESS[6:0] bits. Whether the data is
read from or written into the specified indirect register is determined by
the RWN bit and the data is in the D[7:0] bits. The access status is indi-
cated in the BUSY bit. Refer to Chapter 4.5 Indirect Register Access
Scheme for details about the indirect registers write/read access.

signaling trunk conditioning code in the A,B,C,D bits. When the
GSTRKEN bit is ‘0’, the replacement will be performed on a per-
channel/per-TS basis by setting the STRKEN bit in the corre-
sponding channel/timeslot.
