11.0 Software Register Programming Reference
11.1 Suggested Software Register Programming
There are number of registers whose default values
have been changed to make the sensor operational with
a Digital Still Camera. The registers, there suggested
new values (changes) and reason for there change are
detailed in
(Table 6), on page 31
NOTE!! These are only suggested value changes. De-
pending on the application, there might exist more or
less registers whose default values require modifica-
tions.

11.2 Required Software Register Programming
The MCM20027 SXGA CMOS image sensor
QUIRES the use of use of an external resistor to limit
bias current on the device. This mode requires both the
hardware resistor, and some simple I2C software com-
mands. Please refer to
ue Changes, (Table 7), on page 31
programming information and
Control, (Sec. 8.7), on page 21
the resistor implementation.

Switch to Soft Standby mode (Analog
Reset) and change to external resistor
Switch back to normal mode. Maintain
external resistor use
Normal initial sensor register programming
can be implemented during this period
Restores digital circuitry from State Reset
to 'normal' state.
