Bit Mnemonic Default Description
3 CFSIGN_OPT 0
This bit defines where the CF change of sign detection (APSIGN or VARSIGN) is
implemented.
CFSIGN_OPT Result
0
1
Filtered power signal
On a per-CF basis
[2:0] PGA1 000 These bits define the current channel input gain.
PGA1 Result
000 Gain = 1
1
001 Gain = 2
010 Gain = 4
011 Gain = 8
100 Gain = 16
1
This gain is not recommended in the ADE7166 or ADE7169 because it can create an overranging of the ADC when both current inputs are in opposite phase.
Table 39. Calibration Mode Register (CALMODE, Address 0x3D)
1
Bit Mnemonic Default Description
[7:6] Reserved 0 These bits must be kept at 0 for proper operation.
[5:4] SEL_I_CH 0 These bits define the current channel used for energy measurements.
SEL_I_CH Result
00 Current channel automatically selected by the tampering condition
01 Current channel connected to I
PA
10 Current channel connected to I
PB
11 Current channel automatically selected by the tampering condition
3 V_CH_SHORT 0 Logic 1 shorts the voltage channel to ground.
2 I_CH_SHORT 0 Logic 1 shorts the current channel to ground.
[1:0] Reserved These bits must be kept at 0 for proper operation.
1
This register is not available in the ADE7566 or ADE7569.
INTERRUPT STATUS/ENABLE SFRs
Table 40. Interrupt Status 1 SFR (MIRQSTL, Address 0xDC)
Bit Interrupt Flag Description
7 ADEIRQFLAG
This bit is set if any of the ADE status flags that are enabled to generate an ADE interrupt is set. This bit is
automatically cleared when all of the enabled ADE status flags are cleared.
6 Reserved Reserved.
5 FAULTSIGN
1
Logic 1 indicates that the fault mode has changed according to the configuration of the ACCMODE register.
4 VARSIGN
2
Logic 1 indicates that the reactive power sign has changed according to the configuration of the ACCMODE
register.
3 APSIGN Logic 1 indicates that the active power sign has changed according to the configuration of the ACCMODE register.
2 VANOLOAD
Logic 1 indicates that an interrupt has been caused by apparent power no load detection. This interrupt is
also used to reflect that the part is entering the I
rms
no load mode.
1 RNOLOAD
2
Logic 1 indicates that an interrupt has been caused by reactive power no load detection.
0 APNOLOAD Logic 1 indicates that an interrupt has been caused by active power no load detection.
1
This function is not available in the ADE7566 or ADE7569.
2
This function is not available in the ADE7116, ADE7156, ADE7166, or ADE7566.
