IMPACT IDPU COMMAND SEQUENCES		
Revision:	X	2005-Nov-17

"32 command sequence tables, started by events or by command"		
Each sequence contains up to 128 bytes of commands		
"Commands are formatted like normal commands, except the CCSDS header is replaced with a 2-byte header:"		
	"MSB = command size in bytes, excluding this header"	
	"LSB = coded ApID: 0-7Fh -> 200-27Fh (IMPACT) , 80h-FFh -> 300-37FH (PLASTIC)"	
	Header = 0 -> end of sequence	
	Subsequent bytes are interpreted as the data field of a command packet (after the CCSDS header)	
	Odd-byte length commands should be zero-filled so that headers start on an even byte boundry;	
	 - the fill byte is not included in the command size in the header	
Any number of sequences can be requested at one time (only one request per sequence number)		
	Sequences run to completion. Multiple sequences can run at the same time

20	PLASTIC PS0	PLASTIC	"Disable Entrance system; ""Thruster/Coarse"""
21	PLASTIC Start	PLASTIC	Initializes PLASTIC classifier messages.
22	PLASTIC PS1	PLASTIC	Reduce HV levels - run after selected limit failures 
23	PLASTIC PR0b	PLASTIC	Second half of PR0 (after PR0a)
