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.
