I can't access the CY22150 IIC interface by cy68013
I use the CY22150 to provide clocks. The IIC bus master is cy68013, the slaver is cy22150. I use the
function EZUSB_WriteI2C(ChipID,length,EepromBuf), which is from lib to write data to IIC bus, but the cy22150 didn't send back ACK, after the 8bits ChipID finished.
EepromBuf = 0X09H
EepromBuf = 0X00H
The slaver device address is 0x69H, so EZUSB_WriteI2C(0x69,2,EepromBuf) .
The attachments are schematic.
