The RMS values can be computed by the MPU from the squared current and voltage samples as follows:
Note: N
Other Transfer variables include those available for frequency and phase measurement, and those
reflecting the count of the zero-crossings of the mains voltage and the battery voltage. These transfer
variables are listed in
MAINEDGE_X (CE RAM 0x83) reflects the number of half-cycles accounted for in the last accumulated
interval for the AC signal of the phase specified in the FREQSEL[1:0] field in CECONFIG (CE RAM 0x20[7:6]).
MAINEDGE_X is useful for implementing a real-time clock based on the input AC signal.
