Other Parts Discussed in Thread: LDC1612
Unfortunately the FDC2212 broke during our 6kV ESD-pistol tests, but only the analog part is defect, the chip is still addressable via I2C and all registers are readable.
At the moment I just see that the values in register 0x00 and 0x01 are fixed values (with or without WD/AW error), which could be a possible state (once) in our application at a specific time.
But my question is about register of address 0x19 (ERROR_CONFIG). There I see bit 9 and 8 are set, which leads me to ask you for the meaning of those two bits. In the datasheet I just see “reserved, should be 0x00”. Can you tell me the meaning of those reserved bits? I’m asking because due to your support site I see that the LDC1612 has the same(or similar?) interface and a datasheet with less mistakes than the FDC2212’s datasheet, but in it’s description is no information as well. What are these bits 8 and 9 for ? Could it lead us to this "Analog circuit defect" detection ?
The second question: is there another way to detect if the analog part of the FDC2212 is broken ?
