5.18 Averaging Control Register

The Averaging Control Register controls the digital averaging on the external diode channels.

Bits 1-0 - AVG1[1:0] - Controls the digital averaging that is applied to the External Diode 1 temperature

measurements as shown in Table 5.23.

5.19 Voltage Sampling Configuration Register

The Voltage Sampling Configuration register controls functionality for the source voltage measurement

and Peak Detector circuitry.

Bit 7 - PK_ALERT_THERM - Determines whether the ALERT pin or THERM pin is asserted if the Peak

Detector detects a current spike. If configured to assert the ALERT pin, the PEAK_MASK can block

the pin assertion normally. If configured to assert the THERM pin, it will not be masked.



‘0’ - The Peak Detector circuitry will assert the ALERT pin when a current spike is detected. The

ALERT pin must be configured to operate in Comparator mode or it will not be asserted.



‘1’ (default) - The Peak Detector circuitry will assert the THERM pin when a current spike is

detected.

Bits 3 - 2 - V_QUEUE[1:0] - Determine the number of consecutive measurements that VSOURCE must

exceed the limits before flagging an interrupt.
