Greetings for the Day,
We are facing issues in accessing few registers of TLK10031(Specifically Vendor Specific registers)
We are using TM4CDNCPDT microcontroller with TLK10031 transceiver for 10G repeater application. We are implementing bit-banging to access TLK10031 registers using MDC/MDIO lines.
We can able to read the content of registers belongs to Auto negotiation, PMA/PMD and PCS device type. But we are not able to read the registers belongs to Vendor Specific Device Registers (0x1E). And tried writing data to Vendor Specific Device Registers but we are not sure whether it is working or not as we won't get any response from TLK.
ST and MODE_SEL pins made low.
PD and PRBSEN pins are made HIGH.
MDC clock = 1.25MHz
Is there any specific settings we need to implement for accessing Vendor specific registers? please help us to resolve this issue.
