NOTES ON MAXIMUM RATINGS
1. Exceeding these ratings may cause permanent damage.
Functional operation under these conditions is not implied.
2. Maximum dissipation or 1 second should not be exceeded,
only one output to be tested at any one time.
3. Exposure to absolute maximum ratings for extended
periods may affect device reliablity.
4. Current is defined as negative into the device.

Subgroup
If this bit is set the expansion data input is delayed
by four pixel clocks before it is added to the present
convolver output. It is used in multiple device
systems when the partial window width is 8 pixels.
When this bit is set the internal sum is shifted to the
left by 8 places before being added to the expan-
sion input. It is used when two devices are used,
each in an 8 bit pixel mode, to fabricate a 16 bit
pixel mode.
inputs before entering the line stores. The delays
are always identical on both sets.
When this bit is set the convolver interprets 8 or 16
bit pixels as 2's complement signed numbers
These bits add 0 to 7 additional clock delays to
those selected by Register C, bits 3:1.
