• Manufacturer: Zarlink Semiconductor

Data Sheet
*Note: Only Bit 7-0 will be used for per-channel message mode.
*Note: The last channel (Ch255 or Ch511) of the backplane output streams BSTo60 to BSTo63 or BSTo58 to BSTo63 contains invalid output data when operated
in the 16Mb/s or 32Mb/s mode respectively. Avoid using the last channel of these streams for the "local-to-backplane" switching.

Backplane Source Control Bit: When this bit is low, the "local-to-backplane"
switching is enabled and the source is from the local input port.
Backplane TM Bits: These two bits control the backplane outputs
Backplane Source Stream Address Bits: The binary value of these 6 bits repre-
sents the local data input stream number.
Source Channel Address Bits: The binary value of these 7 bits represents the
local input channel number.
