Steven Cartmell	061795c489	Move in_critical_section implementation into the HAL - Add function to HAL hal_in_critical_section() - Wrap assert in FEATURE_UVISOR macro	2018-01-09 10:41:29 +00:00
Steven Cartmell	04d2f3de78	Amend critical section function descriptions	2018-01-05 14:55:58 +00:00
Steven Cartmell	a07c07fa63	Update HAL API header information	2018-01-05 14:55:57 +00:00
Steven Cartmell	07a394ee8b	Add Critical Section HAL API specification - Define header functions for Critical Section HAL API - hal_critical_section_enter() - hal_critical_section_exit() - Add weak default implementation for HAL API. The default implementation matches the previous behaviour stored in mbed_critical: - The first call to enter a critical section stores the state of interrupts before disabling and each successive call re-disables interrupts. - The last call (non-nested) will restore the IRQ state that was set on the enter to the critical section. Nested calls are ignored. - Add function 'core_util_in_critical_section' to User facing API to determine if the program is currently in a critical section, instead of depending on 'core_util_interrupts_enabled'.	2018-01-05 14:53:51 +00:00
