Unsigned Default Description
0x01 WATTHR R 24 S 0 Reads Wh accumulator without reset.
0x02 RWATTHR R 24 S 0 Reads Wh accumulator with reset.
0x03 LWATTHR R 24 S 0 Reads Wh accumulator synchronous to line cycle.
0x04 VARHR
1
R 24 S 0 Reads VARh accumulator without reset.
0x05 RVARHR
1
R 24 S 0 Reads VARh accumulator with reset.
0x06 LVARHR
1
R 24 S 0 Reads VARh accumulator synchronous to line cycle.
0x07 VAHR R 24 S 0
Reads VAh accumulator without reset. If the VARMSCFCON bit in the
MODE2 register (Address 0x0C) is set, this register accumulates I
rms
.
0x08 RVAHR R 24 S 0
Reads VAh accumulator with reset. If the VARMSCFCON bit in the
MODE2 register (Address 0x0C) is set, this register accumulates I
rms
.
0x09 LVAHR R 24 S 0
Reads VAh accumulator synchronous to line cycle. If the VARMSCFCON
bit in the MODE2 register (Address 0x0C) is set, this register accumulates
I
rms
.
