SREFO ADG[1:0] ADEN AZ

Bit7 Bit0

Bit 7 SREFO: Internal Reference Voltage enable flag. (Please refer to Section 10.1)

1 = Internal Reference Voltage is enabled. VR1P = 2/5 REFO, VR2P = 1/5 REFO

0 = Internal Reference Voltage is disabled. VR1P and VR2P are floating.

Bit 3-2 ADG[1:0]: Internal ADC input gain. (Please refer to Section 10.1)

11 = Internal ADC input gain is 7/3

10 = Internal ADC input gain is 2

01 = Internal ADC input gain is 1

00 = Internal ADC input gain is 2/3

Bit 1 ADEN: ADC enable flag. (Please refer to Section 10.1)

1 = ADC is enabled.

0 = ADC is disabled.

Bit 0 AZ: ADC differential input ports short controller. (Please refer to Section 10.1)

1 = ADC differential input ports are short and both connect to INL

(SINL output).

0 = ADC differential input ports are NOT short. The 2 ports connect to INH and INL.

Property

R = Readable bit W = Writable bit U = unimplemented bit

- n = Value at Power On

Reset

‘1’ = Bit is Set ‘0’ = Bit is Cleared X = Bit is unknown

That means the ADC input differential voltage is zero. ADC output should be zero counts. User could

measure ADC offset counts when the AZ register flag is set.
