8.2 Algorithm_Control Registers

Table 8-5 lists the memory-mapped registers for the Algorithm_Control registers. All register offset addresses not listed in Table 8-5 should be considered as reserved locations and the register contents should not be modified.

Table 8-5 ALGORITHM_CONTROL Registers

Offset	Acronym	Register Name	Section
ECh	ALGO_DEBUG1	Algorithm Control Register	Section 8.2.1
EEh	ALGO_DEBUG2	Algorithm Control Register	Section 8.2.2
F0h	CURRENT_PI	Current PI Controller used	Section 8.2.3
F2h	SPEED_PI	Speed PI controller used	Section 8.2.4

Complex bit access types are encoded to fit into small table cells. Table 8-6 shows the codes that are used for access types in this section.
