3. Implementation

The SNAPAVG block is used to get an average of a value with a specific time frame.
The block has two internal count values to enable the block to function on short windows
or longer windows.

TICS is internally limited to positive whole numbers.

On power up if RET is High, then the internal Count2 and Sum2 is set equal to Outputs
CNT and TTL. Otherwise they are set equal to zero. Also, internal Count1 and Sum1 is
set to zero on powerup. All three outputs go to zero on powerup also.

When the RES bit is high, then both counters and sums are set equal to zero.

When the hold bit is high, both counters and sums are held at their current value.

If both RES and HLD are low, then:

Every time the block is executed, INP is added to the internal Sum1. Also, the
internal value Count1 is incremented.

When Count1 is greater than TICS, then:

Sum2 = Sum1 / Count1
Count2 is incremented
Sum1 and Count1 is reset to zero.
OUT = Sum2 / Count2
TTL = Sum2
CNT = Count2
