These registers provide the most recently acquired ADC inputs. For the ADC channels that are enabled
with the CS[1-3] bits in the Control 2 register set to 1. Otherwise, the value in the corresponding Current
ADC Data [1-3] register will be all 0s and not reported by the Read Data command. It contains either the
most recently measured sample from automatic datalogging or it contains data that was acquired in
response to a user’s instruction for an immediate ADC conversion. When the DS1616 is not on a
mission, an immediate measurement is acquired by issuing the Read Data command with CSx set to a 1.
After issuing the Read Data command, the value in this register is valid only if the Data Ready (DR) bit
in the Status 2 register is a logic 1.
ADC DATA-HIGH THRESHOLD REGISTERS [1-3]

AH0
AH6
AH5
AH4
AH3
AH2
AH1
These registers determines the high threshold for interrupt generation from the three mux’ed ADC inputs.
If the data is greater than or equal to the value in the corresponding register, an interrupt will be activated
if the Data High Interrupt Enable (AHIE) bit is set to a logic 1.
ADC DATA-LOW THRESHOLD REGISTERS [1-3]
MSb
AL7
LSb
AL0
AL6
AL5
AL4
AL3
AL2
AL1
These registers determines the low threshold for interrupt generation from the three mux’ed ADC inputs.
If the data is less than or equal to the value in the corresponding register, an interrupt will be activated if
the Data Low Interrupt Enable (ALIE) bit is set to a logic 1.

CSx -
Channel Select [0-3] - The value of these bits determines which channels are enabled. A 1 in the
CSx bit enables the channel for data collection, recording and reporting. A 0 in the CSx bit disables the
channel so data will not be taken, recorded, or reported. This causes a common problem in retrieving
data, if the CSx bit is set to 0, the datalog and histogram data will not be downloaded from the DS1616.
ALIE
- ADC Data Low Interrupt Enable - When set to a logic 1, this bit permits the ADC Data Low Flag
[1-3] (ALFx[1-3]) in the Status 2 register to assert
INT
. When the ALIE bit is set to logic 0, the ALF bit
does not initiate the
INT
signal.
AHIE
- ADC Data High Interrupt Enable - When set to a logic 1, this bit permits the ADC Data High
Flag [1-3] (AHFx[1-3]) in the Status 2 register to assert
INT
. When the AHIE bit is set to logic 0, the
AHF bit does not initiate the
INT
signal.
