def makeDelayPacket(ID, delay):
pkt = makeWritePacket(ID, xl320.XL320_DELAY_TIME, delay)<EOL>return pkt<EOL>
It is the delay time per data value that takes from the transmission of
Instruction Packet until the return of Status Packet.
0 to 254 (0xFE) can be used, and the delay time per data value is 2 usec.
That is to say, if the data value is 10, 20 usec is delayed. The initial
value is 250 (0xFA) (i.e., 0.5 msec).
