7.7.4 Internal_Algorithm_Configuration Registers

INTERNAL_ALGORITHM_CONFIGURATION Registers lists the memory-mapped registers for the Internal_Algorithm_Configuration registers. All register offset addresses not listed in INTERNAL_ALGORITHM_CONFIGURATION Registers should be considered as reserved locations and the register contents should not be modified.

Table 7-41 INTERNAL_ALGORITHM_CONFIGURATION Registers

Address	Acronym	Register Name	Section
A0h	INT_ALGO_1	Internal Algorithm Configuration 1	INT_ALGO_1 Register (Address = A0h) [Reset = X]
A2h	INT_ALGO_2	Internal Algorithm Configuration 2	INT_ALGO_2 Register (Address = A2h) [Reset = 00000000h]

Complex bit access types are encoded to fit into small table cells. Internal_Algorithm_Configuration Access Type Codes shows the codes that are used for access types in this section.
