Default
Name
DAPWDN: DAC power-down ON/OFF
ADPW: ADC power-down ON/OFF
VRNMOD: Used to set the VD output timing before the VD input timing.
VCNTCR: Sets the V counter reset timing.
HDPOQ: Switches the HD output polarity.
VDPOQ: Switches the VD output polarity.
HDPOL: Switches the HPLL HD input polarity.
Bit
0 (default): DAC power-down ON
0: ADC power-down ON
0 (default): VD outputs VD input signal.
1: Because the VD signal is generated internally, the VD output timing can be before the VD input
0 (default): Resets at H counter = 0.
1: Reset on falling edge of HDOUT
0 (default): Negative polarity (HDOTD = 0), same polarity as the input HD (HDSELB = 1 and
1: Positive polarity (HDOTD = 0), opposite polarity from the input HD (HDSELB = 1 and HDPO =
1: Positive polarity (VNSOFF = 1 or VRNMOD = 1), opposite polarity from the input VD (VNSOFF
0 (default): Same polarity as the input HD
0 (default): Negative polarity (VNSOFF = 1 or VRNMOD = 1), same polarity as the input VD
0), or same polarity as the input HD (HDSELB = 1 and HDPO = 1)
= 0, VRNMOD = 0 and VDPO = 0), or same polarity as the input VD (VNSOFF = 0, VRNMOD =
0 and VDPO = 1)
