;bit10		SWAP	By setting this bit to Logic 1 the analog inputs V2P and V2N are connected to ADC 1 and the
;			analog inputs V1P and V1N are connected to ADC 2.
;bit9		DISCH2	ADC 2 (Channel 2)inputs are internally shorted together.
;bit8		DISCH1	ADC 1 (Channel 1)inputs are internally shorted together.
;bit7		CMODE	Setting this bit to a Logic 1 places the chip in calibration mode.
;bit6		SWRST	Software Chip Reset.A data transfer should not take place to the ADE7756 for at least 18 μs
;			after a software reset.
;bit5		TEMPSEL	The temperature conversion starts when this bit is set to one.This bit is automatically reset to
;			zero when the temperature conversion is finished.
;bit4		ASUSPEND By setting this bit to Logic 1,both ADE7756 ’s A/D converters can be turned off.In normal

;			 pending the clock signal at CLKIN pin.
