reset to 0 (all flags cleared) after a read operation.
Channel 1 Offset Adjust. Bit 6 is not used. Writing to Bits 0 to 5 allows
offsets on Channel 1 to be removed—see the Analog Inputs and CH1OS
Register sections. Writing Logic 1 to the MSB of this register enables the
digital integrator on Channel 1; writing Logic 0 disables the integrator.
The default value of this bit is 0.
Channel 2 Offset Adjust. Bits 6 and 7 are not used. Writing to Bits 0 to 5 of
this register allows offsets on Channel 2 to be removed—see the Analog
Inputs section. Note that the CH2OS register is inverted. To apply a
positive offset, a negative number is written to this register.
PGA Gain Adjust. This 8-bit register is used to adjust the gain selection for
the PGA in Channels 1 and 2—see the Analog Inputs section.
and 2 can be adjusted by writing to this 6-bit register. The valid content
of this twos complement register is between 0x1D to 0x21. At the line
frequency of 60 Hz, this ranges from –2.06° to +0.7°—see the Phase
Compensation section.
