Description
Temperature Channel ADC Enable
This bit is set to 1 by user code to enable the T-ADC
Clearing this bit to 0, powers down the T-ADC

NOTE: These current sources have a tolerance of +-30%.
Not Used
These bits are reserved for future functionality and should not be modified by user code
Temperature Channel ADC Output Coding
This bit is set to 1 by user code to configure T-ADC output coding as unipolar
This bit is cleared to 0 by user code to configure T-ADC output coding as 2’s compliment
Not Used
This bit is reserved for future functionality and should be written 0 by user code

Read/Write
The Temperature Channel ADC Control MMR is an 16-bit register that is used to configure the T-ADC.
The Temperature channel is calibrated to read 0x0000 at 0°K.
The temperature gradient is then 16 codes per degree Celsius
Current Sources Off
Enable 50uA current source on VTEMP+
Enable 50uA current source on GND_SW
Enable 50uA current source on both VTEMP+ and GND_SW
Internal Temperature Sensor
The Temperature gradient is 0.5mV/°C. This is only applicable to the Internal Temperature Sensor
External ( VTEMP, GND_SW)
Shorted Input ( GND_SW, GND_SW)
ADC Reference/136
Internal, 1.2V precision reference selected.
External reference inputs (VREF, GND_SW) selected.
External reference inputs divided by 2 (VREF, GND_SW)/2 selected. This allows an external reference up to
REG_AVDD
(REG_AVDD, GND_SW) divided by 2 selected. Used for external temperature sensor measurements.
