Table 7-57 lists the memory-mapped registers for the System_Status registers. All register offset addresses not listed in Table 7-57 should be considered as reserved locations and the register contents should not be modified.
Offset | Acronym | Register Name | Section |
---|---|---|---|
E4h | ALGO_STATUS | System Status Register | Section 7.8.3.1 |
E6h | MTR_PARAMS | System Status Register | Section 7.8.3.2 |
E8h | ALGO_STATUS_MPET | System Status Register | Section 7.8.3.3 |
Complex bit access types are encoded to fit into small table cells. Table 7-58 shows the codes that are used for access types in this section.
