13-4 Contents of the sense commands
The bit assignment for each status data byte returned
with D7: Status Sense is as follows:
Status (No. 1): First byte
Bit	Status	Remarks
Bit-7	Undefined	Always “1”
Bit-6	Undefined	Always “0”
Bit-5	Short FF/REW	Short FF: Detects the beginning
		of the tape and fast-forwards
		the tape until Stand-By On is
		engaged.
		Short REW: Detects tape end
		and rewinds the tape until
		Stand-By On is engaged.
Bit-4	REC Inhibit	Indicates that a cassette with
		no safety tab has been loaded
		or that recording prohibition
		has been selected with the
		VCR’s memory switch.
Bit-3	Cassette Out	No tape is loaded in the VCR.
Bit-2	Servo Lock	During tape playback, both the
		capstan and drum servo are
		locked.
Bit-1	Undefined	Always “0”
Bit-0	Error	Shows that an invalid command
		has been received. In this status,
		a continuously transmitted
		command will not be accepted.
		To release the Error mode,
		cancel the commands one byte
		at a time with 41: Error Clear. Or
		cancel all commands with 56:
		Clear.
Status (No. 2) Second byte
Bit	Status	Remarks
Bit-7	EE	Externally input video signals
		are output.
Bit-6	A1 EE Mode	Externally input audio (A1)
		signals are output.
Bit-5	Video Mute	Video signals are muted
		(returned from the DS micro-
		processor).
Bit-4	Audio Mute	Audio signals are muted
		(returned from the AUDIO
		microprocessor.).
Bit-3	Warning	Shows that the VCR is in the
		Auto-Off mode.

Bit-2	DEW	Condensation.
Bit-1	Tape Begin	The tape winding start sensor
		is detected.
