3.9.2.a.8 Black (bit 10)
In case B
LACK
is set to 1, the internal black signal will be held high continuously. As
a consequence, the column amplifiers are disconnected from the busses, the busses are
set to the voltage given by D
AC
_
DARK
and the output of the amplifier equals the
voltages from the offset DACs.
3.9.2.a.9 Reset_all (bit 11)
In case R
ESET
_
ALL
is set to 1, all the pixels are simultaneously put in a ‘reset’ state. In
this state, the pixels behave logarithmically with light intensity. If this state is
combined with one of the NDR modes, the sensor can be used in a non-integrating,
logarithmic mode with high dynamic range.
3.9.2.b
N
ROF
_
PIXELS
register
After the internal X_
SYNC
is generated (start of the pixel readout of a particular row),
the P
IXEL
_
VALID
signal goes high. The P
IXEL
_
VALID
signal goes low when the pixel
counter reaches the value loaded in the N
ROF
_
PIXEL
register and an EOL pulse is
generated. Due to the fact that 2 pixels are addressed at each internal clock cycle the
amount of pixels read out in one row = 2*(N
ROF
_
PIXEL
+ 1).
3.9.2.c
N
ROF
_
LINES
register
After the internal Y
L
_
SYNC
is generated (start of the frame readout with Y_
START
),
the line counter increases with each Y_
CLOCK
pulse until it reaches the value loaded
in the N
ROF
_
LINES
register and an EOF pulse is generated. In NDR mode 2, the line
counter increments only every two Y_
CLOCK
pulses and the EOF pulse shows up only
after the readout of the row indicated by the right shift register.
3.9.2.d
I
NT
_
TIME
register
When the Y_
START
pulse is applied (start of the frame readout), the sequencer will
generate the Y
L
_
SYNC
pulse for the left Y-shift register. This loads the left Y-shift
register with the pointer loaded in Y_
REG
register. At each Y_
CLOCK
pulse, the
pointer shifts to the next row and the integration time counter increases (increment
only every two Y_
CLOCK
pulses in NDR mode 2) until it reaches the value loaded in
the I
NT
_
TIME
register. At that moment, the Y
R
_
SYNC
pulse for the right Y-shift
register is generated which loads the right Y-shift register with the pointer loaded in
Y_
REG
register
(Figure
18).
