	---help---
		Use the BASEPRI register to enable and disable interrupts. By

		usually results in hardfaults when supervisor calls are made.
		Though, these hardfaults are properly handled by the RTOS, the
		hardfaults can confuse some debuggers. With the BASEPRI
		register, these hardfaults, will be avoided. For more details see

		architectures.
