This register provides the link number and time-slot number used to access the
transmit channel provision RAM. Writing to this register triggers an indirect
register access and transfers the contents of the Indirect Channel Data register to
an internal holding register.
TSLOT[4:0]:
The indirect time-slot number bits (TSLOT[4:0]) indicate the time-slot to be
configured or interrogated in the indirect access. For a channelised T1/J1
link, time-slots 1 to 24 are valid. For a channelised E1 link, time-slots 1 to 31
are valid. For unchannelised or unframed links, only time-slot 0 is valid.
LINK[6:0]:
The indirect link number bits (LINK[6:0]) select amongst the 84 transmit links
to be configured or interrogated in the indirect access.
