CLK_Compress_On
compression clock active
compression module is brought to low power state
Prefilter B_Comb
horizontal scaling factor exceeds 3 (only functioning if bit 1 is also set to logic 1);
this bit switches prefilter B to 13 taps
prefilter B is as described for bit 1
Prefilter B_On/Off
horizontal scaling factor exceeds 2; the prefilter with 7 taps is switched on
prefilter B is bypassed
Prefilter A_On/Off
prefilter A with 3 taps is on; must be set to logic 1 when bit 2 is set to logic 1 to
obtain the overall wanted frequency response
prefilter A is bypassed

PARAMETER
PIX_nr0 to PIX_nr2
3 LSBs of 10 bits pixel number for autoexposure control (7 LSBs in register 0xC6)
Shutter_Update_Buffer
update of the shutter speed is buffered
no buffering (immediately destroying of the current video frame)
Resume
video processing and PPG are switched of; if a VGA sensor is selected the vertical
transport pulses are not switched off but this must be done by selecting a PAL
sensor (register 0xC2 bit 0)
PGG pulses generated
