i want to read a certain ADV7619's register of 0x03,but no IIC ACK .
CS keep low;
ALSB keep low；
main IIC Address is 0x98 ;
The IIC read and write device is FPGA ,written by Verilog HDL. It is test by read and write a 24c02,and works well.
i don't know why it can't get ADV7619's iic ACK ! ?
hope to get response,thank you
