The Status register indicates a variety of conditions within the chip. Writing a '1' to a Status register bit will
clear that bit if the condition that set it has been removed. Writing a '0' to any bit has no effect.
The Mask register is used to control the activation of the INT pin. Writing a '1' to a Mask register bit will allow
the corresponding Status register bit to activate the INT pin when set.

Data Ready. During conversion, this bit indicates that low-rate results have been updated.
It indicates completion of other commands and the reset sequence.
Current Out of Range. Set when the measured current would cause the I1 ( I2 ) register to
overflow.
Voltage Out of Range. Set when the measured voltage would cause the V1 ( V2 ) register
to overflow.
Conversion Ready. Indicates that sample rate (output word rate) results have been updat-
ed.
RMS Current Out of Range. Set when RMS current would cause the I1
ter to overflow.

Energy Out of Range. Set when average power would cause P1
Indicates when the Temperature register ( T ) has been updated.
Modulator oscillation has been detected in the voltage1 (voltage2) A/D.
Modulator oscillation has been detected in the current1 (current2) A/D.
Low Supply Detect. Set when the voltage on the PFMON pin falls below the specified low
level. The LSD bit cannot be reset until the voltage rises above the specified high level.
Frequency Updated. Indicates the Epsilon register has been updated.
Invalid Command. Normally logic 1. Set to 0 when an invalid command is received. It may
also indicate loss of serial command synchronization and the part may need to be re-ini-
tialized.
