I am configuring LS1021A in RMII mode. Initialization steps in Reference manual says -
Set MIIMADD = 0x0000_nn11 (TBICON, where nn=TBIPA)
When read through reference manual, I could understand that - In order to access any TBI register, I have to load it's address in MIIMADD register. But I don't understand what value I should assign to TBIPA.
TBI's Physical address is stored in TBIPA register.
How can I know TBI's Physical address?
