1: 480/fs (default)
DVTMA: Digital Volume A Soft Transition Time Setting
0: 256/fs
1: 512/fs (default)
This is the transition time between DVLA7-0 bits = FFH and 00H.
DVTMB: Digital Volume B Soft Transition Time Setting
0: 256/fs
1: 512/fs (default)
This is the transition time between DVLB7-0 bits = FFH and 00H.
PMVCM: VCOM Power Management
0: Power down (default)
1: Power up
PMVCM bit must be “1” when one of bocks is powered-up. PMVCM bit can only be “0” when all power
management bits are “0”.
