R is read, and W is write.
32 ZP = 24- or 20-bit signed or unsigned register that is transmitted as a 32-bit word with 8 or 12 MSBs, respectively, padded with 0s. 32 SE = 24-bit signed register that
is transmitted as a 32-bit word sign extended to 32 bits. 16 ZP = 10-bit unsigned register that is transmitted as a 16-bit word with six MSBs padded with 0s.
U is unsigned register, and S is signed register in twos complement format.
N/A is not applicable.

Description
These bits contain the peak value determined in the current channel.
When this bit is set to 1, Phase A current generated IPEAKVAL[23:0] value.
When this bit is set to 1, Phase B current generated IPEAKVAL[23:0] value.
When this bit is set to 1, Phase C current generated IPEAKVAL[23:0] value.
These bits are always 0.

Description
These bits contain the peak value determined in the voltage channel.
When this bit is set to 1, Phase A voltage generated VPEAKVAL[23:0] value.
When this bit is set to 1, Phase B voltage generated VPEAKVAL[23:0] value.
When this bit is set to 1, Phase C voltage generated VPEAKVAL[23:0] value.
These bits are always 0.

Mnemonic
AEHF
Default Value
0
Description
When this bit is set to 1, it indicates that Bit 30 of any one of the total active energy
registers (AWATTHR, BWATTHR, or CWATTHR) has changed.

FREHF
0
0
This bit is always 0.
When this bit is set to 1, it indicates that Bit 30 of any one of the fundamental
reactive energy registers, AFVARHR, BFVARHR, or CFVARHR, has changed.
4
VAEHF
0
When this bit is set to 1, it indicates that Bit 30 of any one of the apparent energy
registers (AVAHR, BVAHR, or CVAHR) has changed.
5
LENERGY
0
When this bit is set to 1, in line energy accumulation mode, it indicates the end of an
integration over an integer number of half line cycles set in the LINECYC register.
6
REVAPA
0
When this bit is set to 1, it indicates that the Phase A active power identified by Bit 6
(REVAPSEL) in the ACCMODE register (total or fundamental) has changed sign. The
sign itself is indicated in Bit 0 (AWSIGN) of the PHSIGN register (see Table 46).
7
REVAPB
0
When this bit is set to 1, it indicates that the Phase B active power identified by Bit 6
(REVAPSEL) in the ACCMODE register (total or fundamental) has changed sign. The
sign itself is indicated in Bit 1 (BWSIGN) of the PHSIGN register (see Table 46).
8
REVAPC
0
When this bit is set to 1, it indicates that the Phase C active power identified by Bit 6
(REVAPSEL) in the ACCMODE register (total or fundamental) has changed sign. The
sign itself is indicated in Bit 2 (CWSIGN) of the PHSIGN register (see Table 46).
