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 1-0

Unimplemented:

Read as ‘0’

Note 1:

The UART Baud Rate bits are only available on system version 0xFA14 and later. Previous versions have

the baud rate fixed at 115200. The baud rate is only changed at system power-up, so a Save To Flash

command is required after changing the baud rate.

Unimplemented:

Read as ‘0‘

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)
