Hardware access control registers

Implementations

impl Accessctrl

pub const unsafe fn from_ptr(ptr: *mut ()) -> Self

pub const fn as_ptr(&self) -> *mut ()

pub const fn lock(self) -> Reg<Lock, RW>

Once a LOCK bit is written to 1, ACCESSCTRL silently ignores writes from that master. LOCK is writable only by a Secure, Privileged processor or debugger. LOCK bits are only writable when their value is zero. Once set, they can never be cleared, except by a full reset of ACCESSCTRL Setting the LOCK bit does not affect whether an access raises a bus error. Unprivileged writes, or writes from the DMA, will continue to raise bus errors. All other accesses will continue not to.

pub const fn force_core_ns(self) -> Reg<ForceCoreNs, RW>

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.

pub const fn cfgreset(self) -> Reg<Cfgreset, RW>

Write 1 to reset all ACCESSCTRL configuration, except for the LOCK and FORCE_CORE_NS registers. This bit is used in the RP2350 bootrom to quickly restore ACCESSCTRL to a known state during the boot path. Note that, like all registers in ACCESSCTRL, this register is not writable when the writer’s corresponding LOCK bit is set, therefore a master which has been locked out of ACCESSCTRL can not use the CFGRESET register to disturb its contents.

pub const fn gpio_nsmask0(self) -> Reg<u32, RW>

Control whether GPIO0…31 are accessible to Non-secure code. Writable only by a Secure, Privileged processor or debugger. 0 -> Secure access only 1 -> Secure + Non-secure access
