H1CONTROL
Register Description
Divide CLI Input Clock by 2. 1 = Divide by 2.
H1 Signal Control: Polarity [0](0 = Inversion, 1 = No Inversion).
H1 Positive Edge Location [6:1]. H1 Negative Edge Location [12:7].
H3 Signal Control: Polarity [0](0 = Inversion, 1 = No Inversion).
H3 Positive Edge Location [6:1]. H3 Negative Edge Location [12:7].
RG Signal Control: Polarity [0](0 = Inversion, 1 = No Inversion).
RG Positive Edge Location [6:1]. RG Negative Edge Location [12:7].
Retime HBLK to Internal H1/H3 Clocks. H1 Retime [0]. H3 Retime [1].
Preferred setting is 1 for each bit. Setting each bit to 1 will add one cycle delay
to HBLK toggle positions.
Drive Strength Control for H1 [2:0], H2 [5:3], H3 [8:6], H4 [11:9], and
RG [14:12]. Drive Current Values: 0 = Off, 1 = 4.3 mA, 2 = 8.6 mA,
3 = 12.9 mA, 4 = 17.2 mA, 5 = 21.5 mA, 6 = 25.8 mA, 7 = 30.1 mA.
SHP/SHD Sample Control: SHP Sampling Location [5:0].
SHD Sampling Location [11:6].
DOUT Phase Control [5:0]. DCLK Mode [6]. DOUTDELAY [8:7].

TRIGGER
Register Description
Trigger for VSUB [0], MSHUT [1], STROBE [2], Exposure [3], and
Readout [4]. Note that to trigger the readout to automatically occur after the
exposure period, both exposure and readout should be triggered together.
Number of Fields to Suppress the SUBCK Pulses after the VSG Line.
Number of Fields to Suppress the SUBCK and VSG Pulses.
Set = 1 to disable the VD/HD outputs during exposure (when >1 field).
Number of SUBCK Pulses to Suppress after VSG Line.
Number of SUBCK Pulses per Field.
SUBCK Pulse Start Polarity.
First SUBCK Pulse. Toggle Position 1 [11:0]. Toggle Position 2 [23:0].
Second SUBCK Pulse. Toggle Position 1 [11:0]. Toggle Position 2 [23:0].
