TV/VTR output selection control signal
* P.OFF, Shifting to T,Standby: "Low" output.
* Shifting to VV from EE: "High" output.
* The condition is inverted whenever the TV/VCR Key is received.
LED ON/OFF control terminal.
"High": ON
"Low": OFF
LED ON/OFF control terminal.
"High": ON
"Low": OFF
Timer-Bus signal for peripheral ICs control: Data input
ROM Correction confirmation mode:
* ROM correction setting bit is "ON": "High".
* ROM correction setting bit is "OFF": "Low" is existed.
(Other than ROM Correction confirmation mode, this terminal is the output
terminal of internal clock for main clock adjustment.:Outputting the 125Hz.)
The rotation direction control terminal of the capstan driver.
*RVS="High"
*FWD="Low".
LED ON/OFF control terminal.
"High": ON
"Low": OFF
Power supply terminal for the capstan motor control.
(Conpared with the driver reference voltage, when it is "low", current will be cut. Also when
it is "high", the rotation speed will be accelerated.)
Power supply terminal of the cylinder motor control:
(Conpared with the driver reference voltage, when it is "high", current will be cut.
Also when it is "low", the rotation speed will be accelerated. (Max:2.8V))
LED ON/OFF control terminal.
"High": ON
"Low": OFF
Input terminal of the S.Reel pulse.
Input terminal of the T.Reel pulse.
Linear Audio REC/ERASE ON/OFF control terminal. (FULL ERASE ON/OFF control is
combined with)
*When recording the linear audio, the "Low" is output synchronizing with D.REC signal for
IC3001.
Output mode: REC(ADUB/AV-INSERT)
*When the recording starts, "Low" is output at 140-160m sec. after D.REC (H) for IC3001
has been shifted to "High" from "Low".
*When the recording stops, the "High" is output at 0-20m sec. after D.REC for IC3001
has being shifted to "low" from "High".
LED ON/OFF control terminal.
"High": ON
"Low": OFF
Terminal for Power ON/OFF control.
POWER is ON: "High"
* During Mechanism Initial Operation: "High".
* After Mechanism Initial Opeation: "Low".
