7.3 Internal Register Space – Base Address 1
These registers are 32 bits wide and are the Port Registers and LRAM of the SiI3124. Access to these registers is through the
PCI Memory space. Register descriptions that follow specify the address offset for Port 0; subsequent port registers are at
2000
H
offset increments, i.e., the upper 2 bits of the 15-bit address offset is the Port number (0-3).
