Other Parts Discussed in Thread: FDC2114
Hi,
The FDC2114 datasheet says "Setting register CONFIG.INTB_DIS to b1 disables the INTB function and holds the INTB pin high", whereas when I set CONFIG.INTB_DIS to b1 it is held low.
When I enable it with these configurations:
CONFIG: 0x1E01
ERROR_CONFIG: 1
MUX_CONFIG: 0x020D
Output of INTB pin remains low. I found the only event that would cause a deviation in INTB to high for a brief moment (ranging from 1.16 to 42ms) is the reading of the STATUS register.
Can I ask if anyone else has encountered the same issue, if there is any fix, or if I should assume the device is faulty and need to get a new one?
Figure 1: The output of INTB measured on an oscilloscope, the program reads the STATUS register every second, which accounts for the intermittent spikes in voltage
Figure 2: When CONFIG.INTB_DIS is set to b1. INTB essentially flatlines, contrary to datasheet.
