For AFE4300 calibration

Other Parts Discussed in Thread: AFE4300

Dear Sir

May I ask a question for AFE4300 BCM calibration?

When I am trying to program AFE4300 software, I want to do BCM software calibration. I saw TI software demo to Initialize the BCM Module for 100 ohm reference calibration and 1000 ohm reference calibration with different ISW_MUX and VSW_MUX selection. I do not know what's the difference.

For 100 ohm:

writeRegister(ISW_MATRIX,0x0101); //Reference resistors RP0 and RN0

writeRegister(VSW_MATRIX,0x0101); //Reference resistors RP0 and RN0

For 1000 ohm:

writeRegister(ISW_MATRIX,0x0202); //Reference resistors RP1 and RN1

writeRegister(VSW_MATRIX,0x0202); //Reference resistors RP1 and RN1

Hope your kind guidance. Thanks.

Best Regards

Hongwei
