7.5.8.1 (D7h) MFR_SPECIFIC_07

The MFR_SPECIFIC_07 command is used to configure the internal loop compensation for both channels. The MFR_SPECIFIC_07 command must be accessed through Write Word/Read Word transactions.

MFR_SPECIFIC_07 is a paged register. In order to access MFR_SPECIFIC_07 command for channel A, PAGE must be set to 00h. In order to access the MFR_SPECIFIC_07 register for channel B, PAGE must be set to 01h.
