This register contains either the data to be written into the internal TPSC
registers when a write request is initiated or the data read from the internal TPSC
registers when a read request has completed. During normal operation, if data is
to be written to the internal registers, the byte to be written must be written into
this Data register before the target register's address and R/WB=0 is written into
the Address/Control register, initiating the access. If data is to be read from the
internal registers, only the target register's address and R/WB=1 is written into
the Address/Control register, initiating the request. After 480 ns, this register will
contain the requested data byte.
The internal TPSC registers control the per-timeslot functions on the Transmit
PCM data, provide the per-timeslot Transmit IDLE Code, and provide the per-
timeslot Transmit signaling control and the alternate signaling bits. The functions
are allocated within the registers as follows:
