Command Code:

cmdCTR_SET = 42

The Packet:

0		1		2		3		4		5
address		4		cmdCTR_SET		CtrID		COUNTH		COUNTL

CtrID -	Index of the counter.  Range is 0-7.
COUNTH -	High byte of count
COUNTL -	Low byte of count

Description:

This command sets the 2-byte value for a counter.  An ID that is out of range will generate an error message.  There is no reply packet.

This BrainStem module has eight 2-byte counters.  Reflexes may use these counters to record events.  A counter generates a raw input when the count reaches zero after a decrement or increment operation.

If the command packet does not have a COUNTH and COUNTL byte, the Stem will send a cmdCTR_SET reply packet with the counter ID and current COUNTH and COUNTL bytes.
