In ADSP-BF60x Blackfin Hardware Reference,

SEC_CCTL.NMIEN:

NMI Enable.

The SEC_CCTLn.NMIENbit controls NMI propagation to the core.

When the SEC_CCTLn.NMIENbit is enabled, the SCI allows NMIs to

propagate to the core for servicing.

 

Does it mean that I can disable NMI on bf606?

 

I pull up SYS_NMI_n pin with a 1k resistor, but u-boot on my board always enter NMI ISR.

I don't know why, so i want to disable NMI.

 

Thank you.
