3.2 Global Parameters
Each MCC has a set of global parameters in the DPRAM that are common to all channels within that
MCC. The global parameters define a base for the transmit and receive circular BD tables, the maximum
buffer size, and interrupt queue adresses.The global parameters provide the common functionality for all
active channels on each MCC. The MCC1 global parameter resides in the DPRAM at address 0x8700.
Table 10 describe the global channel parameters of MCC1.
