	The upper context is automatically saved when entering a trap or interrupt.
	Need to save the lower context as well and copy the PCXI CSA ID into
	pxCurrentTCB->pxTopOfStack. Only Lower Context CSA IDs may be saved to the
	TCB of a task.

	Call vTaskSwitchContext to select the next task, note that this changes the
	value of pxCurrentTCB so that it needs to be reloaded.

	Call vPortSetMPURegisterSetOne to change the MPU mapping for the task
	that has just been switched in.

	Load the context of the task.
	Need to restore the lower context by loading the CSA from
	pxCurrentTCB->pxTopOfStack into PCXI (effectively changing the call stack).
	In the Interrupt handler post-amble, RSLCX will restore the lower context
	of the task. RFE will restore the upper context of the task, jump to the
	return address and restore the previous state of interrupts being
	enabled/disabled. */
