Description

RST

R/W

Reset Bit. Setting this bit to '1' generates a system reset that is the

same as power-on reset.

Resets all registers to default values.

0h = Normal Operation

1h = System Reset sets registers to default values

This bit self-clears.

RSTACC

R/W

Resets the contents of accumulation registers ENERGY and

CHARGE to 0

0h = Normal Operation

1h = Clears registers to default values for ENERGY and CHARGE

registers

13-6

CONVDLY

R/W

Sets the Delay for initial ADC conversion in steps of 2ms.

0h = 0s

1h = 2ms

FFh = 510ms

3h = Reserved

4h = Triggered temperature, single shot

5h = Triggered temperature and bus voltage, single shot

6h = Triggered temperature and current, single shot

7h = Triggered temperature, current and bus voltage, single shot

8h = Shutdown

9h = Continuous bus voltage only

Ah = Reserved

Bh = Reserved

Ch = Continuous temperature only

Dh = Continuous bus voltage and temperature

Eh = Continuous temperature and current

Fh = Continuous temperature, current, and bus voltage
