ALERT0 PIN ROUTING (PAGE 0x11)

All the registers from this page allow routing of the alert signals

generated by the corresponding inputs/channels to the GPIO3/

ALERT0 pin of the device. The upper byte controls the high

alerts routing, whereas the lower byte controls the low alerts

routing.

VINx ALERT0 Register (Register 0x12)

This 16-bit register allows routing of the VINx generated alerts

to the ALERT0 pin.

Temperature Sensor (TSENSEx) ALERT0 Register

(Register 0x14)

This 16-bit register allows routing of the temperature sensor

generated alerts to the ALERT0 pin.

Current Sensor (ISENSEx) ALERT0 Register (Register 0x15)

This 16-bit register allows routing of the current sensor

generated alerts to the ALERT0 pin.

Supply and BI-VOUTxMON ALERT0 Register (Register 0x18)

This 16-bit register allows routing of the supply channels and

the bipolar DAC monitor channels generated alerts to the

ALERT0 pin.

RSx+MON ALERT0 Register (Register 0x19)

This 16-bit register allows routing of the RSx+MON alerts to the

ALERT0 pin.

INTLIMITx and AVss/AVDD ALERT0 Register (Register 0x1A)

This 16-bit register allows routing of the closed-loop integrator

limit and AVSS/AVDD alerts to the ALERT0 pin.
