EXTERN vUSB_ISR
PUBLIC vUSBISREntry
; Wrapper for the USB interrupt service routine. This can cause a
; context switch so requires an assembly wrapper.
; Defines the portSAVE_CONTEXT and portRESTORE_CONTEXT macros.
#include "ISR_Support.h"
vUSBISREntry:
portSAVE_CONTEXT ; Save the context of the current task.
bl vUSB_ISR ; Call the ISR routine.
portRESTORE_CONTEXT ; Restore the context of the current task -
; which may be different to the task that
; was interrupted.
