Description

Control whether debugger, DMA, core 0 and core 1 can access PLL_USB, and at what security/privilege levels they can do so.

Defaults to Secure, Privileged processor or debug access only.

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.

Fields

NSU

If 1, and NSP is also set, PLL_USB can be accessed from a Non-secure, Unprivileged context.

This bit is writable from a Non-secure, Privileged context, if and only if the NSP bit is set.

NSP

If 1, PLL_USB can be accessed from a Non-secure, Privileged context.

SU

If 1, and SP is also set, PLL_USB can be accessed from a Secure, Unprivileged context.

SP

If 1, PLL_USB can be accessed from a Secure, Privileged context.

CORE0

If 1, PLL_USB can be accessed by core 0, at security/privilege levels permitted by SP/NSP/SU/NSU in this register.

CORE1

If 1, PLL_USB can be accessed by core 1, at security/privilege levels permitted by SP/NSP/SU/NSU in this register.

DMA

If 1, PLL_USB can be accessed by the DMA, at security/privilege levels permitted by SP/NSP/SU/NSU in this register.

DBG

If 1, PLL_USB can be accessed by the debugger, at security/privilege levels permitted by SP/NSP/SU/NSU in this register.
