Other Parts Discussed in Thread: MSP430FR2676,
I have a setup with the FDC2212 communicating with the MSP430FR2676 via I2C. I have not been able to get the FDC2212 to drive the LC oscillator and receive data. I have set up the code to write the registers in the same order per the Application example in the data sheet. I have confirmed that the MSP430 is writing to the FDC2212 registers properly. However, I notice when I reset the device through either a SW reset command or by shutting it down via hardware and reenabling it, the registers seem to not be set at their default values according to the datasheet. For example, when I power on my unit, the FDC2212 is in shutdown mode by having the SD pin be pulled up to the supply pin. When the MSP430 initializes everything, it drives the shutdown pin low to enable the FDC2212. After enabling the FDC2212, I read the CONFIG register to see what values it is showing. Below are screenshots of what the value should be and what I am reading. I can share more register reads, if needed.
Data Sheet
MSP430 Read
As can be seen, bit 0 according to the datasheet should be set to 1 on a reset. I am reading it as a 0. There are a few other bits that are not reading properly as well.
