VIN ALERT0 Routing and VIN ALERT1 Routing
Subregisters (Address 0x13 and Address 0x14)
The 16-bit VIN ALERT0 and VIN ALERT1 subregisters enable
the routing of alerts from the analog input channels, VIN0 to
VIN7, to the GPIO0/ALERT0 and GPIO1/ALERT1 pins (see
Table 23 and Table 24).
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 temperature
sensor alerts, see the Temperature Sensor Alert Routing Subregister
(Address 0x21) section.
