Functional Description and Application Information
4.2.3.1
For device options with the current sense module not available, the following considerations are to be made.
4.2.3.1.1
4.2.3.1.2
The Current Sense Register must remain in default (0x00) state.
The Conversion Control Register - Bit 9 must always be written 0.
The Conversion Complete Register - Bit 9 must be ignored.
The ADC Data Result Reg 9 must be ignored.
