7.4 Internal_Algorithm_Configuration Registers

Table 7-29 lists the memory-mapped registers for the Internal_Algorithm_Configuration registers. All register offset addresses not listed in Table 7-29 should be considered as reserved locations and the register contents should not be modified.

Table 7-29 INTERNAL_ALGORITHM_CONFIGURATION Registers

Offset	Acronym	Register Name	Section
A0h	INT_ALGO_1	Internal Algorithm Configuration1	Section 7.4.1
A2h	INT_ALGO_2	Internal Algorithm Configuration2	Section 7.4.2

Complex bit access types are encoded to fit into small table cells. Table 7-30 shows the codes that are used for access types in this section.
