Motorola MTX series - Table 3-11. Register Summary

Register Summary
Table 3-11 shows a summary of the CSR.
Note The table only shows addresses for accesses to the upper Falcon.
To get the addresses for accesses to the lower Falcon, add 4 to the
address shown. Since the only way to write to the lower Falcon’s
internal register set is to duplicate what is written to the upper
Falcon, only the addresses shown in the table should be used for
writes to them. Writes to the external register set are not
duplicated from upper to lower, so writes to them can be via the
upper or lower Falcon.
