TSLOT[3:0]
The indirect time-slot number bits (TSLOT[3:0]) indicate the time-slot to be configured or
interrogated in the indirect access. For the data incoming to the SSWT, time-slots 1 to 12 are
valid. Indices 0 and 13 to 15 are invalid. An invalid index will result in immediate
deassertion of the busy bit and undefined results in the DINSEL register. The following table
shows valid TSLOT values.

PGSEL
The PGSEL specifies the Control page of the Space switch control block in an indirect MUX
Control Access. When PGSEL is logic 0, Control page 0 is selected. When PGSEL is 1,
Control page 1 is selected.
RWB
The indirect access control bit (RWB) selects between a configure (write) or interrogate
(read) access to the space switch control blocks. The address to the control registers is
constructed from the DOUTSEL[5:0] and TSLOT[3:0] fields. Writing a logic zero to RWB
triggers an indirect write operation. Data to be written is taken from the DINSEL[6:0] data
register. Writing a logic one to RWB triggers an indirect read operation. Addressing of the
switch control block is the same as in an indirect write operation. The data read can be found
in DINSEL[6:0] after the BUSY bit has cleared.
