Controlling CLPOB Clamp Pulse Timing
Up to two individual CLPOB pulses can be programmed per line
using the CLPOBTOGx (x = 1, 2, 3, 4) registers in Table XII.
As shown in Figure 19, these registers reference the 12-bit HD
counter. Additional CLPOBENn (n = 0, 1, 2, 3, 4) registers are

the CLPOB pulse in each region of the CCD. Figure 23 shows
an example of disabling the CLPOB pulse while operating in
CCD region 1.
