1 * = don’t care.

2 VID transient period is the time following any VID change, including entry into and exit from deeper sleep mode. The duration of VID transient period is the same as

that of PWRGD masking time.

3 CCM stands for continuous current mode, and DCM stands for discontinuous current mode.
