NAME
	STOP -- Stop processor execution (PRIVILEGED)

SYNOPSIS
	STOP	#<data:16>

FUNCTION
	Immediate data is moved to SR. PC is set to next instruction,
	and the processor stops fetch and execution of instruction.
	Execution restarts if if a TRACE exception, an interruption, or
	a RESET takes place.
	When STOP is executed, a TRACE exception is generated (if T = 1).
	An interruption is allowed if it level is higher than current one.
	An external RESET always will generate a RESET exception.
	If bit S is set to zero by the immediate data, execution of this
	instruction will generate a "privilege violation".
