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-
register must be set to 1 (see Table 27). On power-up, the
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 ALERT0 Routing and VIN ALERT1
Routing Subregisters (Address 0x13 and Address 0x14) section.
