SIGNAL NAME I/O
O Reserved.
VSC_ON-H
VSC_DATA O Reserved.
High output of period to becoming of V.REC.ST-H High from VCR
REC_MUTE-H O
REC demand and VCR PLAY inside.
Supply side reel sensor input.
REEL_S I
The reel is detected whether rotating when the tape running.
REEL_T I Winding up reel sensor input.
Control terminal for A/V Recording Circuit On/Off.
V.REC.ST-H O H: At the time of start recording.
L: Except the above
NC O Reserved.
NC O Reserved.
FEW I The FZTAT writing protecting input (Protect it by "L" input).
X2 O 32kHz Oscillation.
32kHz Oscillation.
X1 I When reset returns, the presence of 32kHz Crystal is confirmed.
It is: There are no 32kHz clock count: It counts the clock with 10MHz.
_RESET I Reset input.
OSC1 I 10MHz Oscillation.
VSS - GND.
OSC2 O 10MHz Oscillation.
VCL I Flat and smooth-ized capacity connection terminal.
FZTAT writing mode setting input
MD0 I
(When "L" is input, it is a writing mode).
NC O Reserved.
CAP_LIMIT O Control terminal for Capstan Motor. (Switching Drive output current)
NC O Reserved. (L output)
NC O Reserved. (L output)
NC O Reserved. (L output)
POWER ON is directed to the HOST microcomputer by the TAPE IN
detection
T.IN-POWER_ON-H at the POWER OFF state.
O
WAKE UP) L: In the following cases, excluding.
H: It TAPE IN detects with POWER OFF 〜 Made that
receives P. ON command (29H) from MPEG.
For CENTER LED control
L: P.FAIL and PSAVE mode
H: Usually
CENT_LED O
CENTER LED is controlled for the power saving. It is assumed L
when the P.SAVE mode
shifts P.FAIL, and assumes H when returning.
BOT is usually invalid for tape IN detection in the low power
consumption mode.
BOT2 I The state is observed in the low power consumption mode in the state
of tape EJECT,
and P.ON and tape IN works by the H-->L detection.
