description: |
|
||
An array of two integers for configuring the chip measurement mode.
|
||
|
||
The first integer defines the bits 2..0 in the control register. In all
|
||
cases the internal temperature and supply voltage are measured. In
|
||
addition the following input measurements are enabled per mode:
|
||
As per the datasheet,

b[2:0] | Mode [2:0] | Mode Description
|
||
0 | 0 0 0 | V1, V2, TR2 (Default)
|

|
||
7 | 1 1 1 | V1, V2, V3, V4
|

-------------------------------------------
|
||
The second integer defines the bits 4..3 in the control register. This
|
||
allows a subset of the measurements to be enabled:
