This bit controls the monitoring loop. Setting the bit to 0 stops the
monitoring loop and puts the device into shutdown mode. The I
interface is still active during the shutdown mode. Setting the bit to 1 starts
the monitoring cycle. All high/low limits should be set before setting this
bit to 1.
This bit is used to enable or disable the interrupt output. Setting the bit to
1 enabes the interrupt output; setting the bit to 0 disables the interrupt
output.
—
This bit is used to clear the interrupt output when it is set to high. It will not
affect the interrupt status register. The monitoring loop will not start until
the bit is set to 0.
This bit controls the internal clock frequency. Setting the bit to 1 changes
the clock frequency to 51.2kHz from 61.4kHz. This can improve the
measurement accuracy when the power-line frequency is at 50Hz.
This bit reduces the conversion rate by a factor of four when it is set to 1.
—
This bit is used as a reset signal for the register initialization. The 1 of this
bit will reset all the register values into the power-up default mode,
including bit 7 itself.
A 1 indicates either a high or low limit has been exceeded at the 2.5V
input.
A 1 indicates either a high or low limit has been exceeded at the 12V
input.
A 1 indicates either a high or low limit has been exceeded at the 3.3V
input.
A 1 indicates either a high or low limit has been exceeded at the V
A 1 indicates either a high or low limit has been exceeded at the internal
temperature sensor. The conditions that will generate and clear this bit
depend on the temperature interrupt mode selected by bits 0 and 1 in the
temperature configuration register.
