Description
These unused bits are always zero.
F0 is a square wave at the exact fundamental input frequency.
This unused bit is always zero.
Normally zero. Becomes one when VB remains below SAG_THR for
SAG_CNT samples. Does not return to zero until VB rises above
SAG_THR.
Normally zero. Becomes one when VA remains below SAG_THR for
SAG_CNT samples. Does not return to zero until VA rises above
SAG_THR.

Table 82: CECONFIG Register
When this bit is set, control of temperature compensation is
enabled for the 71M6x01 Isolated Sensor Interface.
When 1, the MPU controls temperature compensation via the
GAIN_ADJn registers (CE RAM 0x40-0x42), when 0, the CE is in
control.
When 1, XPULSE produces a pulse for each zero-crossing of
the mains phase selected by FREQSEL[1:0] , which can be used
to interrupt the MPU.
When 1, activates YPULSE output when a sag condition is
detected.
The number of consecutive voltage samples below SAG_THR
(CE RAM 0x24) before a sag alarm is declared. The default value
is equivalent to 100 ms.
