Where is ETH_PHY_INTN

[pkoevesdi]

In the reference Manual of STMH730, on Table 543, page 2825, there's a Port "ETH_PHY_INTN" listed. Where ist that port? Or where can I configure the GPIO to use for it? I cannot find anything in the datasheet.

This is likely error in the RM. The Data sheet for H730 does not mention a pin function ETH_PHY_INTN.

If you want to receive interrupts from your PHY interrupt output, it can be connected to any suitable pin.

Hello,

I'm checking that internally. It could be a typo or a miss.

Yes, but the RM says "Bit 3 PHYIS: PHY Interrupt
This bit is set when rising edge is detected on the ETH_PHY_INTN input. This bit is cleared when this register is read."

So, to use this function, I'd have to tell, where I have my INT input connected. So, either there's a dedicated pin function for it, which we cannot find in the datasheet, or I'd expect some register to tell, which GPIO I use for it.

Thank You for looking at it. For the first I assume, I can take any GPIO. Please tell here, if there's a special pin / function needed.

The ETH IP supports multiple products. Some of them may have a dedicated PHY interrupt input, then it goes into that register bit.  Let's wait for SofLit to check.

Any news on this?

I will keep you informed as soon as I have a feedback.

Hello,

Just got the feedback regarding this topic and thank you for your patience.

The ETH_PHY_INTN pin is not available and it will be removed from the documentation. Meanwhile, this functionality could be managed by GPIO and EXTI.

Thank you!
