bit 12

ZCD_INV:

Zero Crossing Detection Output Inverse

= ZCD is inverted

= ZCD is not inverted (Default)

bit 11

ZCD_PULS:

Zero Crossing Detection Pulse mode

= ZCD output is 100 µs pulses on zero crossings

= ZCD Output changes logic state on zero crossings (Default)

bit 10

ZCD_OUTPUT_DIS:

Disable the Zero Crossing output pin

= ZCD output is disabled

= ZCD output is enabled (Default)

bit 9

Unimplemented:

Read as ‘0’

bit 8

SINGLE_WIRE:

Single-Wire Enable bit

= Single-wire transmission is enabled

= Single-wire transmission is disabled (Default)

bit 7

TEMPCOMP:

Temperature-Compensation Enable bit

= Temperature compensation is enabled

= Temperature compensation is disabled (Default)

bit 6-5

RESET <1:0>:

Reset mode setting for ADCs

= Both I1 and V1 are in Reset mode

= V1 ADC is in Reset mode

= I1 ADC is in Reset mode

= Neither ADC is in Reset mode (Default)

bit 4-3

SHUTDOWN <1:0>:

Shutdown mode setting for ADCs

= Both I1 and V1 are in Shutdown

= V1 ADC is in Shutdown

= I1 ADC is in Shutdown

= Neither ADC is in Shutdown (Default)

bit 2

VREFEXT:

Internal Voltage Reference Shutdown Control

= Internal Voltage Reference Disabled

= Internal Voltage Reference Enabled (Default)

bit 1

PWM_CNTRL:

PWM Control

= PWM is turned on

= PWM is turned off (Default)

bit 0

ENRG_CNTRL:

Energy Accumulation Control bit

= Energy is ON and all registers are accumulating

= Energy accumulation is turned off and all energy accumulation registers are reset to 0 (Default)

Note 1:

The baud rate is only changed at system power-up, so a Save To Flash command is required after

changing the baud rate.
