Name	Description	Applicable Boards
Sedi	0 = single-ended	Elton, Stevie, Jethro, Ziggy
​	1 = differential ended	Elton, Stevie, Jethro
Lowch	low channel, 0-5(Single ended)	Elton, Stevie, Jethro, Ziggy
	low channel, 0-2(Differential ended)	Elton, Stevie, Jethro
Highch	high channel, 0-5(Single ended)	Elton, Stevie, Jethro, Ziggy
	high channel, 0-2(Differential ended)	Elton, Stevie, Jethro
Currentch	channel number 0-5 for current conversion	Elton, Stevie, Jethro, Ziggy
ScanEnable	0 = sample, 1 = scan	Elton, Stevie, Jethro, Ziggy
Adtrig	00 = software initiated A/D conversion 01 = external GPIO pin is used to trigger A/D conversion	Elton, Stevie, Jethro, Ziggy
Adsel	0 = A/D circuit 0, 1 = AD circuit 1	Elton, Stevie, Jethro, Ziggy
Adref	00 = external reference (set to 3.3V ) 01 = internal bandgap reference	Elton, Stevie, Jethro, Ziggy
Adtag	0 = upper 4 bits of 16-bit value = 0000 1 = upper 4 bits of 16-bit value contain A/D channel number	Elton, Stevie, Jethro, Ziggy
Adchset	ADCHSET = 0: Selects channel number for current conversion ADCHSET = 1: Selects high/low channel number	Elton, Stevie, Jethro, Ziggy
Adres	0 - No oversampling, A/D resolution = 12 bits 1 - A/D resolution = 14 bits 2 - A/D resolution = 15 bits 3 - A/D resolution = 16 bits	Elton, Stevie, Jethro, Ziggy
Adsamples	Number of samples to be accumulated to calculate average sample: 1, 2, 4, 8, 6, 32, 64,128, 256, 512 and 1024 (Please refer section 45.6.2.10 in SAMD51 datasheet for more information)	Elton, Stevie, Jethro, Ziggy
