In ADSP-BF60x Blackfin Hardware Reference,
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.
