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.
Note
This register is not byte addressable. Writing to this register modifies all the bits in the register.
Byte selection using byte enable signals (CBEB[3:0]) are not implemented. However, when all
four byte enables are negated, no access is made to this 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 link, time-slots 1 to 24 are valid. For
