Hardware access control registers

Modules

adc0

Control whether debugger, DMA, core 0 and core 1 can access ADC0, and at what security/privilege levels they can do so. Defaults to Secure access from any master. This register is writable only from a Secure, Privileged processor or debugger, with the exception of the NSU bit, which becomes Non-secure-Privileged-writable when the NSP bit is set.

force_core_ns

Force core 1’s bus accesses to always be Non-secure, no matter the core’s internal state. Useful for schemes where one core is designated as the Non-secure core, since some peripherals may filter individual registers internally based on security state but not on master ID.
