Only the loop controller device (U1) uses the resistor to AGND for MSEL1 to program the (B1h) USER_DATA_01 (COMPENSATION_CONFIG) values to set the following voltage loop and current loop gains. The MSEL1 pin of the loop follower devices are not used. For options other than the EEPROM code (MSEL1 shorted to AGND or MSEL1 to AGND resistor code 0), the current and voltage loop zero and pole frequencies are scaled with the programmed switching frequency. See Section 7.2.2.4 for more details.
