Register 0x604: TAPI Indirect Channel Provisioning Register
The Indirect Channel Provisioning Register provides the channel number used to access the TAPI-
12 channel provisioning RAM. Writing to this register triggers an indirect channel register access.
CHAN[9:0]
RWB
BUSY
The indirect channel number bits (CHAN[9:0]) indicate the channel to be configured or
interrogated in the indirect access.
The Read/Write Bar (RWB) bit selects between a provisioning/unprovisioning operation (write)
or a query operation (read). Writing a logic 0 to RWB triggers the provisioning or
unprovisioning of the channel specified by CHAN[9:0]. Writing a logic 1 to RWB triggers a
query of the channel specified by CHAN[9:0].
The indirect access status bit (BUSY) reports the progress of an indirect access. BUSY is set
high when this register is written to trigger an indirect access, and will stay high until the access
is complete. At which point, BUSY will be set low. This register should be polled to determine
when data from an indirect read operation is available or to determine when a new indirect
write operation may commence.
