Description
When this bit is 0, it signifies that the internal voltage reference is used in the ADCs.
When this bit is 1, an external reference is connected to the Pin 17 REF
When this bit is 0, the SS /HSA pin can be toggled three times to activate the SPI port. If I
active serial port, this bit must be set to 1 to lock it in. From this moment on, spurious toggling of
the SS pin and an eventual switch into using the SPI port are no longer possible. If SPI is the
active serial port, any write to the CONFIG2[7:0] register locks the port. From this moment on, a
switch into using I
when theADE7878 changes PSMx power modes.
Reserved. These bits do not manage any functionality.
Description
00 = HSDC transmits sixteen 32-bit words in the following order: IAWV, VAWV, IBWV,
VBWV, ICWV, VCWV, one 32-bit word equal to INWV, AVA, BVA, CVA, AWATT, BWATT,
CWATT, AVAR, BVAR, and CVAR.
01 = HSDC transmits seven instantaneous values of currents and voltages: IAWV, VAWV,
IBWV, VBWV, ICWV, VCWV, and INWV.
10 = HSDC transmits nine instantaneous values of phase powers: AVA, BVA, CVA, AWATT,
BWATT, CWATT, AVAR, BVAR, and CVAR.
11 = reserved. If set, the ADE7878 behaves as if HXFER[1:0] = 00.
0: HSACTIVE output pin is active low.
1: HSACTIVE output pin is active high.
Reserved. These bits do not manage any functionality.
Description
Threshold is put at a value corresponding to full scale multiplied by LPOIL/8.
The measurement period is (LPLINE + 1)/50 seconds.
