		format. The most significant nibble is the device ID, while the remaining five nibbles
		make up the device serial number.

	Example	The following example translates the HIGH_BYTE-MID_BYTE-LOW_BYTE output
		into the device code-serial number format:		Returned value.
		1.	C02B33h	Returned value.
		2.	C = Attenuator	First nibble is the device code.
