PRODUCTION DATA
SYSTEM_STATUS Registers lists the memory-mapped registers for the System_Status registers. All register offset addresses not listed in SYSTEM_STATUS Registers should be considered as reserved locations and the register contents should not be modified.
Address | Acronym | Register Name | Section |
---|---|---|---|
E4h | ALGO_STATUS | System Status Register | ALGO_STATUS Register (Address = E4h) [Reset = 00000000h] |
E6h | MTR_PARAMS | System Status Register | MTR_PARAMS Register (Address = E6h) [Reset = 00000000h] |
E8h | ALGO_STATUS_MPET | System Status Register | ALGO_STATUS_MPET Register (Address = E8h) [Reset = 00000000h] |
Complex bit access types are encoded to fit into small table cells. System_Status Access Type Codes shows the codes that are used for access types in this section.
