CLAMP REGISTER 0
CR0 (CR00–CR07)
(Address (SR4–SR0) = 06H)
Figure 21 shows the various operations under the control of
Clamp Register 0.
CR0 BIT DESCRIPTION
Clamp Level/16 (CR00–CR06)
To perform an accurate AGC gain operation, it is necessary
to know to what level the user is clamping the black level. This
black level is then subtracted from the 10-bit ADC output
before gaining. It is then added on again afterwards. It should
be noted that this register is seven bit and will hold the value of
Clamp Value/16.
Reserved (CR07)
Zero must be written to this bit.
CLAMP REGISTER 1
CR1 (CR10–CR17)
(Address (SR4–SR0) = 07H)
Figure 22 shows the various operations under the control of
Clamp Register 1.
CR1 BIT DESCRIPTION
Fine Clamp On Time (CR10–CR12)
There are three fine clamp circuits on the chip. This word
controls the number of clock cycles for which the fine clamps
are switched on per video line. The clamp is switched on after a
SYNC pulse is received on the SYNC_IN pin, provided the
relevant enabling bit is set (see CR16).
Coarse Clamp On Time (CR13–CR15)
There are three coarse clamp circuits on the chip. This I
2C
word controls the number of clock cycles for which the fine
clamps are switched on per video line. The clamp is switched on
after a SYNC pulse is received on the SYNC_IN pin, provided
the relevant enabling bit is set (see CR16).
Synchronize Clamps (CR16)
Setting this bit to “1” forces the clamps to wait until the next
sync pulse before switching on.
Reserved (CR17)
Zero must be written to this bit.
