While reviewing the PN7642 datasheet, I discovered that the chip provides configuration for observing digital and analog debug signals via APIs. I then tried to configure it using an evaluation board and found the corresponding API in the SDK (located in PN76_Testbus.h). However, based solely on the description in that .h file, I don't know how to use these APIs. For example, what parameters should I pass in to observe the signals I want to see? Are there any relevant documents for this scenario?
Hello, I found an image (CTS_TESTBUS_Signals.png) in the file you mentioned, but I noticed that the digital signals in this image do not correspond one-to-one with the digital signals in the PN7642 datasheet. How can I obtain the complete mapping table?
Hello, I have read this document before, but it does not provide clear instructions. For example, after reviewing the documentation, I am still unclear about what parameters should be passed to these APIs to output the ADC IQ signals or other digital/analog signals.
Under the "doc" folder in the SDK, there is "PN76-FW-apiguide".
Unfortunately, we do not have any publicly available documentation that describes this in more detail.
NXP provides additional information in UM11566, which includes the register information about the TestBus Select and Value registers. Since this document is under NDA, access is restricted.
If you require this information, please complete the NDA process with NXP. After NDA approval, the document can be downloaded from the "Secure" under Documentation section of the PN7642 product page on the NXP website.
