I Capacitor Connection terminal of Slicer Ref Voltage Generator Circuit
I Slicer Composite Video Signal Input Terminal.
- Testing terminal A. ( Connected to GND )
Unused terminal
O SECAM CHROMA signal input terminal for SECAM SIGNAL SUPER IMPOSE.
O Unused terminal
AUDIO SYSTEM (TUNER PRESET) select terminal.
O AUDIO SYSTEM = BG, DK: High is Output.
AUDIO SYSTEM = I, M: Low is Output.
AGC gain selection signal for tuner CH selection.
I/O During digital AFC is working at TUNER PRESET mode: Low (AGC is high speed)
Other than above: Hi-Z (AGC is normal speed)
O Unused terminal
O Unused terminal

O
EEPROM control terminal: clock output
O Peripheral IC control Timer-Bus signal: data output
I Peripheral IC control Timer-Bus signal: data input
O Peripheral IC control Timer-Bus signal: clock output
O AV1 Chip/FM Audio IC serial communication terminal(IIC).
I/O AV1 Chip/FM Audio IC serial communication terminal(IIC).
Since there are 2 function controls,port function is divided into 2 as shown below.
(1) Normal mode/Service mode : Fixed Output(NC) = L
(2) Test mode: Judge ROM core confirmation. Decide port function.
When ROM core confirm mode: ROM.CORE terminal
When other than ROM core confirm mode: Main clock Adjustment Internal
Osc. Output terminal
O
(3) Test 2 mode:Main clock Adjustment Internal Osc. Output terminal
Control method of each port function is shown as below.
[ROM .CORE terminal]When ROM collection setting bit = ON, Output = High
When ROM collection setting bit = OFF, Output = Low
[Main clock Adjuatment Internal Osc. Output terminal ]
Output : 125Hz
Capstan driver rotating direction control
O
RVS = "High", FWD = "Low"
VTR power control terminal.
When VTR = Power Off, and, DVD = Power Off, Ouput = Low
When VTR peripheral circuit = Power Off/ Timer Standby, Output = Low
O Even when apparently Power is Off, if Mecha or Peripheral circuit operation is
required, output = High
If required: Head cleaning, timer confirmation ( VPS/PDC standby, ACS )
When J.CLK Syscon serial is ON( during J.CLK mode ), even if power is off = High
