CH1OS Register (08H)
The CH1OS register is an 8-bit, read/write enabled register. The MSB of this register is used to switch on/off the digital integrator in
Channel 1, and Bits 0 to 5 indicate the amount of the offset correction in Channel 1. Table VIII summarizes the function of this register.

Bit Mnemonic
Description
0 to 5
OFFSET
The six LSBs of the CH1OS register control the amount of dc offset correction in Channel 1
ADC. The 6-bit offset correction is sign and magnitude coded. Bits 0 to 4 indicate the magnitude
of the offset correction. Bit 5 shows the sign of the offset correction. A 0 in Bit 5 means the
offset correction is positive and a 1 indicates the offset correction is negative.
This bit is unused.
This bit is used to activate the digital integrator on Channel 1. The digital integrator is switched
on by setting this bit. This bit is set to be 1 on default.
