ADE7754
–35–
Operational Mode Register (0Ah)
The general configuration of the ADE7754 is defined by writing to the OPMODE register. Table IX summarizes the functionality of
each bit in the OPMODE register.
Table IX. OPMODE Register
Bit Bit Default
Location Mnemonic Value Description
0 DISHPF 0 The HPFs (high-pass filters) in all current channel inputs are disabled when this bit is set.
1 DISLPF 0 The LPFs (low-pass filters) in all current channel inputs are disabled when this bit is set.
2 DISCF 1 The frequency output CF is disabled when this bit is set.
3-5 DISMOD 0 By setting these bits, ADE7754’s A/D converters can be turned off. In normal operation, these
bits should be left at Logic 0.
DISMOD2 DISMOD1 DISMOD0
000Normal operation.
100Normal operation. By setting this bit to Logic 1, the analog
inputs to current channel are connected to the ADC for voltage
channel and the analog inputs to voltage channel are connected
to the ADC for current channel.
001Current channel A/D converters off.
101Current channel A/D converters off + channels swapped.
010Voltage Channel A/D converters off.
110Voltage Channel A/D converters off + channels swapped.
011ADE7754 in sleep mode.
111ADE7754 powered down.
6SWRST 0 Software Chip Reset. A data transfer to the ADE7754 should not take place for at least 18 µs
after a software reset.
7 RESERVED This is intended for factory testing only and should be left at 0.
