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.
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 the Phase A voltage is
missing.
When this bit is set to 1, it enables an interrupt when a zero crossing on the Phase B voltage is
missing.
When this bit is set to 1, it enables an interrupt when a zero crossing on the Phase C voltage is
missing.
When this bit is set to 1, it enables an interrupt when a zero crossing on the Phase A current is
missing.
Description
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[7:0] 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[7:0] 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[7:0] 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[7:0] register (total or fundamental) changes sign.
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[7:0] register (total or fundamental) changes sign.
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[7:0] 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 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[15:0] register. The type of power used at
the CF1 pin is determined by Bits[2:0] (CF1SEL) in the CFMODE[15:0] register (see Table 39).
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[15:0] register. The type of power used at
the CF2 pin is determined by Bits[5:3] (CF2SEL) in the CFMODE[15:0] register (see Table 39).
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[15:0] register. The type of power used at
the CF3 pin is determined by Bits[8:6] (CF3SEL) in the CFMODE[15:0] register (see Table 39).
When this bit is set to 1, it enables an interrupt when all periodic (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.
