; Wrappers for the serial port interrupt service routines.  These can cause a
; context switch so requires an assembly wrapper.

; Defines the portSAVE_CONTEXT and portRESTORE_CONTEXT macros.
#include "ISR_Support.h"

vUARTRxISRWrapper:

	portSAVE_CONTEXT				; Save the context of the current task.

	jarl	vUARTRxISRHandler, lp	; Call the ISR routine.

vUARTTxISRWrapper:

	portSAVE_CONTEXT				; Save the context of the current task.

	jarl	vUARTTxISRHandler, lp	; Call the ISR routine.

	portRESTORE_CONTEXT				; Restore the context of the current task -
