automatically clears if a subsequent IN4 conversion is within the range set by the HYSTERESIS field in the HYST_IN4

HI_IN4

IN4 Upper Alert Indicator. This bit is set to 1 when a conversion result for IN4 is greater than or equal to the IN4 upper

threshold value. This indicator is only active if the threshold detection is enabled on IN4 (see the Threshold Detection and

Alert Indicators section). This bit is read to clear. When the ALERT_MODE bit in the setup register is set to 1, this bit also

automatically clears if a subsequent IN4 conversion is within the range set by the HYSTERESIS field in the HYST_IN4

[7:0]

INX_CLAMP_FLAG[7:0]

INx Overvoltage Clamp Flags. This field indicates if the INx overvoltage protection clamps are

active because of an overvoltage event. Each bit corresponds to one of the analog inputs (IN0 to

IN7), where INX_CLAMP_FLAG, Bit x corresponds to the INx overvoltage protection clamp status.

INX_CLAMP_FLAG, Bit x is set to 1 when the INx overvoltage protection clamp is active. These bits are

not sticky and are automatically cleared when the corresponding overvoltage protection clamp deactivates.

ALERT_MODE

Alert Mode Select Bit. This bit determines how the upper and lower alert indicators (HI_INn and LO_INn) are cleared

(see the Alert Indicator Registers section).

0x0

R/W

0: hysteresis enabled.

1: hysteresis disabled.

SDO_STATE

SDO State Select Bit. This bit determines the behavior of serial data output(s) at the beginning and end of conversion

mode SPI frames (see the Conversion Mode Timing Diagrams section).

0x0

R/W

0: serial data output(s) hold the final value until the MSB of the next conversion data is clocked out.

1: busy indicator is enabled on the serial data output(s).
