Tool/software:
Hello.
I'm using DP83825I in RMII slave mode. I'm trying to set LED_2 output as 10/100 speed indicator and I have problems - it seems to be working rather like link activity with some kind of filter/latch.
According to datasheet, page 3: "RMII Slave Mode: LED_2(default). This pin can be configured as GPIO using register configuration" modifying register 0x0302 should not be needed.
Then I've written 0x0050 to register 0x0460 (LEDCFG_Register, with notabene confusing description: "LED_2 Control:Selects the source for LED_1") but it did not change the behavior. Value of this register that I'm reading after the reset is also not matching the one from the datasheet (reading: 0x0515, datasheet: 0x10).
I've found https://e2e.ti.com/support/interface-group/interface/f/interface-forum/955765/dp83825i-dp83825i-led-indication-of-led2 thread and tried it, also with no needed effect. In this thread undocumented register 0x0305 register was used (or is it a typo and it should be 0x0302?), there is also write to 0x0460 bits that are described as reserved.
Could I get a more precise description of related PHY registers?
