The DVS_CFG sets the fast slew rate at which
any output voltage changes per SVID SetVID-Fast command. This commanded rate of change does
not apply when the unit is commanded to turn on or to turn off. The unit is mV/μs.

These bits select the Dynamic Voltage Scale (DVS) fast slew rate.
Upon acknowledging a new value written into this register, the new slew rate value
is loaded into SVID (24h) SR_FAST register immediately. See below table for
details. |
