CONFIG_CPU_CORTEX_M_HAS_BASEPRI

(No prompt – not directly user assignable.)

Type: bool

Help

This option signifies the CPU has the BASEPRI register.

The BASEPRI register defines the minimum priority for exception processing. When BASEPRI is set to a nonzero value, it prevents the activation of all exceptions with the same or lower priority level as the BASEPRI value. Always present in CPUs that implement the ARMv7-M or ARM8-M Mainline architectures.

Direct dependencies

ARMV7_M_ARMV8_M_MAINLINE && CPU_CORTEX_M && ARM

(Includes any dependencies from ifs and menus.)
