Addressing
Figure 12b - 2.048 Mbps Add/Drop Mode RPCM
Addressing
4.096 Mbps Mode
The 4.096 Mbps mode has 8 input and 8 output
streams, and 64 channels per stream. Therefore 3
bits are used to address the 8 streams, and 6 bits
are used to address the 64 channels. Figure 13a
shows how the Transmit Path Data Memory is read in
this mode. Each of the 512 input channels is mapped
to an address in the TPDM. CPU reads require the 2
LSBs of the CAR Register, and the 7 LSBs of the
address bus. The source-channel address-value
written in the TPCM requires 9 bits.
Figure 13b shows how the Receive Path Connection
Memory is addressed by the CPU in 4.096 Mbps
mode. Each of the 512 output channels has a
control-address in the RPCM. CPU accesses require
the 2 LSBs of the CAR Register, and the 7 LSBs of
the address bus. Per-channel direction control in this
mode is the same as the 2.048 Mbps Balanced
mode.

8.192 Mbps Mode
The 8.192 Mbps mode has 4 input and 4 output
streams, and 128 channels per stream. Therefore 2
bits are used to address the 4 streams, and 7 bits
are used to address the 128 channels. Figure 14a
shows how the Transmit Path Data Memory is read in
this mode. Each of the 512 input channels is mapped
to an address in the TPDM. CPU reads require the 2
LSBs of the CAR Register, and the 7 LSBs of the
address bus. The source-channel address-value
written in the TPCM requires 9 bits.
