Command Code:

cmdPWINDOW = 53

The Packet:

0		1		2		3		4		5		6
address		5		cmdPWINDOW		OFFSET		INPUT		SPXMIN		SPXMAX

OFFSET -	Reflex vector offset
INPUT -	Input parameter
SPXMIN -	Scratch pad index of Minimum threshold
SPXMAX -	Scratch pad index of Maximum threshold

Description:

This command compares an input parameter to a minimum and maximum threshold.  The minimum and maximum threshold come from the scratch pad.  There is no reply packet.  It generates a raw input based on the result:

OFFSET+0 -- input in window

OFFSET+1 -- input less than minimum threshold

OFFSET+2 -- input greater than maximum threshold

OFFSET+3 -- null

When the minimum is less than the maximum the command acts as a dual comparator with hysteresis.  There is a "dead zone" between the two thresholds where the result is "null".  When the minimum is greater than the maximum, the command acts as a standard window comparator.

See the discussion of Scratch Pad usage for more details.
