Data Sheet
The address range for a particular stream is given by adding the group start address, as indicated in Table 12, to
the appropriate stream offset range, as indicated in Table 13. For example, the Connection Memory address range
for SToB12 operating at 32 Mbps is 00C800-00CFFF; the Connection Memory address range for SToC4 operating
at 8 Mbps is 004400-0045FF.
Each output channel timeslot occupies a range of 4 addresses in the Connection Memories. The timeslot address
offset is illustrated in Table 14. It shows the maximum number of timeslots that a stream can have, but the actual
number of timeslots available depends on the output data rates, as illustrated in Table 1 and Table 13.
