� Example of converting volume register reading to units: If the reading for register 404106 (volume high word) is 12,
and the reading for register 404107 (volume low word) is 34, the volume is 12003.4 liters. 12 * 1000 + 34/10 = 12003.4.
�� Example of converting cycles register reading to units: If the reading for register 404108 (cycles high word)
is 75, and the reading for register 404109 (cycles low word) is 8000, the volume is 758,000 cycles. 75 * 10000
+ 8000 = 758000.
