Shutter_Lower
Address: 0x0e
Access: Read
Reset Value: 0x85
System Test: This test is initiated via the Configuration_Bits register. It performs several tests to
verify that the hardware is functioning correctly. Perform a hardware reset just prior to running
the test. SROM contents and register settings will be lost.
SROM CRC Test: Performs a CRC on the SROM contents. The test is initiated by writing a
particular value to the SROM_Enable register.

Shutter_Upper
Address: 0x0f
Access: Read
Reset Value: 0x00
Data Type: Sixteen bit unsigned integer.
USAGE: Units are clock cycles. Read Shutter_Upper first, then Shutter_Lower. They should be
read consecutively. The shutter is adjusted to keep the average and maximum pixel values within
normal operating ranges. The shutter value is checked and automatically adjusted to a new value
if needed on every frame when operating in default mode. When the shutter adjusts, it changes
by ± 1/16 of the current value. The shutter value can be set manually by setting the AGC mode
to Disable using the Extended_Config register and writing to the Shutter_Maximum_Bound
registers. Because the automatic frame rate feature is related to shutter value. It may also be
appropriate to enable the Fixed Frame Rate mode using the Extended_Config register.
Shown below is a graph of 250 sequentially acquired shutter values, while the sensor was moved
slowly over white paper.

Data_Out_Lower
Address: 0x0c
Access: Read
Reset Value: Undefined
Data_Out_Upper
Address: 0x0d
Access: Read
Reset Value: Undefined
Data Type: Sixteen bit word.
USAGE: Data in these registers come from the system self test or the SROM CRC test. The data
can be read out 0x0d, or 0x0d first, then 0x0c.
