DESCRIPTION
1
When SELPD = 1 this bit has no effect.
When SELPD = 0 this bit controls the global power down:
0 = complete power down, 1 = fully active.
Select correlated double sampling mode: 0 = single ended mode,
1 = CDS mode.
Mono/colour select: 0 = colour, 1 = monochrome operation.
Selective power down: 0 = no individual control,
1 = individual blocks can be disabled (controlled by SELDIS[3:0]).
Offsets PGA output to optimise the ADC range for different polarity sensor
output signals. Zero differential PGA input signal gives:
00 = Zero output
(use for bipolar video)
01 = Zero output
11 = Full-scale negative output
(use for positive going video)
Required when operating in MODE4: 0 = other modes, 1 = MODE4.
Determines the output data format.
00 = 8-bit multiplexed
01 = 8-bit multiplexed (8+8 bits)
11 = 4-bit multiplexed mode (4+4+4+4 bits)
Digitally inverts the polarity of output data.
0 = negative going video gives negative going output,
1 = negative-going video gives positive going output data.
When set powers down the RLCDAC, changing its output to Hi-Z, allowing
VRLC/VBIAS to be externally driven.
Sets the output range of the RLCDAC.
0 = RLCDAC ranges from 0 to AVDD (approximately),
1 = RLCDAC ranges from 0 to VRT (approximately).
Sets the output latency in ADC clock periods.
1 ADC clock period = 2 MCLK periods except in Mode 3 where 1 ADC clock
period = 3 MCLK periods.
00 = Minimum latency
01 = Delay by one ADC clock
period
Controls RLCDAC driving VRLC pin to define single ended signal reference
voltage or Reset Level Clamp voltage. See Electrical Characteristics section
for ranges.
CDS mode reset timing adjust.
00 = Advance 1 MCLK period
01 = Normal
11 = Retard 2 MCLK periods
Monochrome mode channel select.
00 = Red channel select
01 = Green channel select
11 = Reserved
Any write to Software Reset causes all cells to be reset. It is recommended
that a software reset be performed after a power-up before any other register
writes.
Any write to Auto-cycle Reset causes the auto-cycle counter to reset
to RINP. This function is only required when LINEBYLINE = 1.
