Tool/software:
Hi expert,
1. What is the routine software configuration of the internal reference 1p65 is 1.65V and the configuration of 3.3?
2. The example is configured so that the chip vrefH is not connected to 3.3v, the chip sampling is abnormal, and the sampling value is calculated according to the benchmark 1.65 according to the appeal configuration? Why do you need to connect this VREFH to 3.3 when configuring the internal reference?
