CE Status Word
Since the CE_BUSY interrupt occurs at 2520.6Hz, it is desirable to minimize the computation required in the interrupt handler
of the MPU. The CE status word can be read by the MPU at every CE_BUSY interrupt.

Name
CESTATUS
Description
See description of CE status word below
The CE Status Word is useful for generating early warnings to the MPU. It contains sag warnings for phase A, B, and C, as
well as F0, the derived clock operating at the fundamental input frequency. CESTATUS provides information about the status of
voltage and input AC signal frequency, which are useful for generating an early power fail warning to initiate necessary data
storage. CESTATUS represents the status flags for the preceding CE code pass (CE_BUSY interrupt).
Note: The CE does not store sag alarms from one code pass to the next. CESTATUS is refreshed at every CE_BUSY
interrupt and remains valid for up to 100μs after the CE_BUSY interrupt occurs. Unsynchronized read operations of
CESTATUS will yield unreliable results.
The significance of the bits in CESTATUS is shown in the table below:

Description
These unused bits will always be zero.
F0 is a square wave at the exact fundamental input frequency.
Normally zero. Becomes one when |VC| remains below SAG_THR for SAG_CNT
samples. Will not return to zero until |VC| rises above SAG_THR .
Normally zero. Becomes one when |VB| remains below SAG_THR for SAG_CNT
samples. Will not return to zero until |VB| rises above SAG_THR .
Normally zero. Becomes one when |VA| remains below SAG_THR for SAG_CNT
samples. Will not return to zero until |VA} rises above SAG_THR .
These unused bits will always be zero.
For generating proper status information, the CE is initialized by the MPU using SAG_THR (default of 80V RMS at the meter
input if VMAX =600V) and SAG_CNT (default 80 samples). Using the default value for SAG_CNT , the peak-to-peak signal has to
be below SAG_THR value for 32 milliseconds to activate the SAG_X status bits.
