Auxiliary Area Allocations				Appendix D
Address	Bits		Name	Function
A414	02	RS-422A	Parity Error Flag	These error flags turn ON when an error has occurred at the RS-
		Port		422A port.
	03		Framing Error Flag
		Error
	04	Flags	Overrun Error Flag
	05		Timeout Error Flag
	08	RS-422A Port Communications Error Flag		Turns ON when a communications error has occurred at the RS-
				422A port.
	09	RS-422A Port Send Ready Flag (no-protocol		Turns ON when the RS-422A port is ready to send data in no-pro-
		mode)		tocol mode.
	10	RS-422A Port Reception Completed Flag (no-		Turns ON when the RS-422A port has completed the reception in
		protocol mode)		no-protocol mode.
	11	RS-422A Port Reception Overflow Flag (no-pro-		Turns ON when a data overflow occurred during reception
		tocol mode)		through the RS-422A port in no-protocol mode.
	15	RS-422A Port Settings Changing Flag		Turns ON while the RS-422A port’s communications settings are
				being changed.
A415	00 to 15	RS-422A Port Reception Counter (no-protocol		Indicates (in binary) the number of bytes of data received when
		mode)		the RS-422A port is in no-protocol mode.
A500	14	Error Log Pointer Reset and Memory Not Held		The error log pointer in A408 is reset to 0000 hex and Memory
		Flag OFF Bit		Not Held Flag (A404.14) is turned OFF when this bit is turned
				ON.
A502	00	RS-232C Port Restart Bit		Turn this bit ON to restart the RS-232C port.
				This bit is turned OFF automatically when the restart processing
				is completed.
	01	Peripheral Port Restart Bit		Turn this bit ON to restart the peripheral port.
				This bit is turned OFF automatically when the restart processing
				is completed.
	02	RS-422A Port Restart Bit		Turn this bit ON to restart the RS-422A port.
				This bit is turned OFF automatically when the restart processing
				is completed.
A507	00 to 15	Data Trace Period		Data will be traced using the period specified here when tracing
				each cycle is specified from the CX-Programmer.
				0000 hex: Each cycle
				0001 to 000F hex: Every 2 to 16 cycles
A508	09	Differentiate Monitor Completed Flag		Turns ON when the differentiate monitor condition has been
				established during execution of differentiation monitoring.
				(This flag will be turned OFF when differentiation monitoring
				starts.)
	11	Trace Trigger Monitor Flag		Turns ON when a trigger condition is established by the Trace
				Start Bit (A508.14). OFF when the next Data Trace is started by
				the Sampling Start bit (A508.15).
	12	Trace Completed Flag		Turns ON when sampling of a region of trace memory has been
				completed during execution of a Trace.
				Turns OFF when the next time the Sampling Start Bit (A508.15) is
				turned from OFF to ON.
	13	Trace Busy Flag		Turns ON when the Sampling Start Bit (A508.15) is turned from
				OFF to ON. Turns OFF when the trace is completed.
	14	Trace Start Bit		Turn this bit ON to establish the trigger condition. The offset indi-
				cated by the delay value (positive or negative) determines which
				data samples are valid.
	15	Sampling Start Bit		When a data trace is started by turning this bit from OFF to ON
				from the CX-Programmer, the FQM1 will begin storing data in
				Trace Memory by one of the three following methods:
				1) Data is sampled at regular intervals (10 to 2,550 ms).
				2) Data is sampled when TRSM(045) is executed in the program.
				3) Data is sampled at the end of every cycle.
				The operation of A508.15 can be controlled only from the CX-Pro-
				grammer.
A509	15	Constant Cycle Time Exceeded Error Clear Bit		Used to enable the constant cycle time function again after the
				constant cycle time has been exceeded.
A510 to	00 to 15	Macro Area Input Words		Before the subroutine specified in MCRO(099) is executed, the
A514				contents of the five words specified in the operand to be passed
				to the subroutine are stored here.
A515 to	00 to 15	Macro Area Output Words		After the subroutine specified in MCRO(099) has been executed,
A519				the results of the subroutine are transferred to these five words.
