Table 7-36 SENSOR_V0_THRESH (Address 0x19)
BITFIELDTYPEDEFAULTDESCRIPTION
7RESERVEDR/W0x0Reserved.
6:4SENSE_V0_HIR/W0x6GPIO0/V0 sensor upper limit. When the GPIO0 is configured as a voltage sensor, and the voltage measured is above the SENSE_V0_HI, it triggers the V0_SENSOR_HI alarm in the SENSOR_STATUS register. The max reading can be read from VOLTAGE_SENSOR_V0_MAX.
3RESERVEDR/W0x0Reserved.
2:0SENSE_V0_LOR/W0x2GPIO0/V0 sensor lower limit. When the GPIO0 is configured as a voltage sensor, and the voltage measured is below the SENSE_V0_LO, it triggers the V0_SENSOR_LOW alarm in the SENSOR_STATUS register. The min reading can be read from VOLTAGE_SENSOR_V0_MIN.
