%SW6222	--	3111	CFW_STS_NR_SERIAL_LOW	Product serial number low part *

NOTE!

* This marker requires a conversion from decimal to hexadecimal. Example:

CFW_STS_NR_SERIAL_HIGH = 1000: Presented value 1000d is equivalent to 03E8h;CFW_STS_NR_SERIAL_LOW = 2000: Presented value 2000d is equivalent to 07D0h;

To get the product's serial number, concatenate values high and low:

03E8 and 07D0 = 03E807D0h = 65538000d.
