AM4372: TPS65218 nINT pin connection

Part Number: AM4372
Other Parts Discussed in Thread: TPS65218

Hi,

Can nINT(TPS65218) connect to either nNMI(AM4372) or GPIO(AM4372)?

According to the manual(p.4) below, nINT is connected to GPIO,but AM437xEVM is connected to nNMI.
I would like to know which is the recommended connection.

Hi,

TPS65218 nINT pin is connected to AM437x nNMI on all EVM's. I recommend you follow this connection.

Hi Biser-san,

Thank you for your reply.
My customer wants to input another error signal on the nNMI pin.
If possible, connect the nINT to the GPIO and add another signal to the nNMI.
When connecting nINT to GPIO as shown below, what's the point of note?

This depends on what software you will use.

Thank you.
Is it that I can connect GPIO if I pay attention to SW?

Best regards,
