CONFIG_CPU_CORTEX_M_HAS_SPLIM
¶
(No prompt – not directly user assignable.)
Type: bool
Help¶
This option signifies the CPU has the MSPLIM, PSPLIM registers.
The stack pointer limit registers, MSPLIM, PSPLIM, limit the extend to which the Main and Process Stack Pointers, respectively, can descend. MSPLIM, PSPLIM are always present in ARMv8-M MCUs that implement the ARMv8-M Main Extension (Mainline).
In an ARMv8-M Mainline implementation with the Security Extension the MSPLIM, PSPLIM registers have additional Secure instances. In an ARMv8-M Baseline implementation with the Security Extension the MSPLIM, PSPLIM registers have only Secure instances.
Direct dependencies¶
