Part Number: DP83TC812R-Q1
Tool/software:
Hello, we use the TIDA020047 development board and need to use the 83TC812 chip for network data transmission. However, after we configure the registers of the chip, we cannot get the output RGMII interface data. We see that there is no waveform through the oscilloscope. I don't know if the register configuration is incorrect, please help us check it:
