Temperature Sensor Subregister (Address 0x20)

The 16-bit temperature sensor subregister enables temperature

sensor conversions and digital filtering of the temperature sensor

channel. To enable temperature sensor conversions or digital

filtering, the corresponding bit in the temperature sensor sub-

temperature sensor subregister contains all 0s by default.

Temperature Sensor Alert Routing Subregister

(Address 0x21)

The 16-bit temperature sensor alert routing subregister enables

the routing of alerts from the internal temperature sensor to the

GPIO0/ALERT0 and GPIO1/ALERT1 pins (see Table 28).

For information about how to configure the GPIO0/ALERT0 and

GPIO1/ALERT1 pins as alert pins, see the Digital I/O Function

Subregister (Address 0x02) section and the Digital Output Driver

Subregister (Address 0x01) section.

For information about how to enable routing of the analog input

channel alerts, see the VIN Filter Subregister (Address 0x13)

and Conversion Delay Control Subregister (Address 0x14)

section.
