Description
When this bit is set to 1, it enables an interrupt when Bit 30 of any one of the apparent
energy registers (AVAHR, BVAHR, or CVAHR) changes.
When this bit is set to 1, in line energy accumulation mode, it enables an interrupt at the end
of an integration over an integer number of half line cycles set in the LINECYC register.
When this bit is set to 1, it enables an interrupt when the Phase A active power identified by
Bit 6 (REVAPSEL) in the ACCMODE register (total or fundamental) changes sign.
When this bit is set to 1, it enables an interrupt when the Phase B active power identified by
Bit 6 (REVAPSEL) in the ACCMODE register (total or fundamental) changes sign.
When this bit is set to 1, it enables an interrupt when the Phase C active power identified by
Bit 6 (REVAPSEL) in the ACCMODE register (total or fundamental) changes sign.
When this bit is set to 1, it enables an interrupt when the sum of all phase powers in the CF1
datapath changes sign.
When this bit is set to 1, it enables an interrupt when the Phase A reactive power identified
by Bit 7 (REVRPSEL) in the ACCMODE register (total or fundamental) changes sign. Setting
this bit to1 does not have any consequence for ADE7854.
When this bit is set to 1, it enables an interrupt when the Phase B reactive power identified
by Bit 7 (REVRPSEL) in the ACCMODE register (total or fundamental) changes sign. Setting
this bit to1 does not have any consequence for ADE7854.
When this bit is set to 1, it enables an interrupt when the Phase C reactive power identified
by Bit 7 (REVRPSEL) in the ACCMODE register (total or fundamental) changes sign. Setting
this bit to1 does not have any consequence for ADE7854.
When this bit is set to 1, it enables an interrupt when the sum of all phase powers in the CF2
datapath changes sign.
When this bit is set to 1, it enables an interrupt when a high-to-low transition occurs at the
CF1 pin, that is, an active low pulse is generated. The interrupt can be enabled even if the
CF1 output is disabled by setting Bit 9 (CF1DIS) to 1 in the CFMODE register. The type of
power used at the CF1 pin is determined by Bits[2:0] (CF1SEL[2:0]) in the CFMODE register
(see Table 45).
When this bit is set to 1, it enables an interrupt when a high-to-low transition occurs at CF2
pin, that is, an active low pulse is generated. The interrupt may be enabled even if the CF2
output is disabled by setting Bit 10 (CF2DIS) to 1 in the CFMODE register. The type of power
used at the CF2 pin is determined by Bits[5:3] (CF2SEL[2:0]) in the CFMODE register (see Table 45).
When this bit is set to 1, it enables an interrupt when a high to low transition occurs at CF3
pin, that is, an active low pulse is generated. The interrupt may be enabled even if the CF3
output is disabled by setting Bit 11 (CF3DIS) to 1 in the CFMODE register. The type of power
used at the CF3 pin is determined by Bits[8:6] (CF3SEL[2:0]) in the CFMODE register (see Table 45).
When this bit is set to 1, it enables an interrupt when all periodical (at 8 kHz rate) DSP
computations finish.
When this bit is set to 1, it enables an interrupt when the sum of all phase powers in the CF3
datapath changes sign.
Reserved. These bits do not manage any functionality.
Description
When this bit is set to 1, it enables an interrupt when at least one phase enters no load
condition based on total active and reactive powers.
When this bit is set to 1, it enables an interrupt when at least one phase enters no load
condition based on fundamental active and reactive powers. Setting this bit to 1 does not
have any consequence for ADE7854, ADE7858, and ADE7868.
When this bit is set to 1, it enables an interrupt when at least one phase enters no load
condition based on apparent power.
When this bit is set to 1, it enables an interrupt when a zero crossing on Phase A voltage is
missing.
When this bit is set to 1, it enables an interrupt when a zero crossing on Phase B voltage is
missing.
