NOTE FOR SUPPLYING POWER
(1)Timing of power supplying to AC pin
The internal circuit of M35071-XXXSP/FP is reset when the level
of the auto clear input pin AC is “L”. This pin in hysteresis input with
the pull-up resistor.
The timing about power supplying of AC pin is shown in Figure 16.
DATA REQUIRED FOR MASK ROM ORDERING
Please send the following data for mask orders.
(1) M35071-XXXSP/FP mask ROM order confirmation form
(2) 20P4B mask specification form
(3) 20P2Q-A mask specification from
(4) ROM data (EPROM 3 sets)
(5) Floppy disks containing the character font generating program
+ character data
PRECAUTION FOR USE
Notes on noise and latch-up
In order to avoid noise and latch-up, connect a bypass capacitor
(
0.1
μ
F) directly between the V
DD1
pin and V
SS1
pin, and the V
DD2
pin and V
SS2
pin using a heavy wire.

, it needs to
keep V

time; tw of the AC pin for more than 1ms.
Start inputting from microcomputer after AC pin supply voltage
becomes more than 0.8

and keeping 200ms wait time.
(2)Timing of power supplying to V
DD1
and V
DD2
.
Supply power to V
DD1
and V
DD2
at the same time.
Note for waveform timing of the horizontal signals to the HOR pin
Set horizontal synchronous signal edge
waveform timing to under
5ns and input to HOR pin.
Set only the side which set by B/F register waveform timing under
5ns and input to HOR pin.
: Set front porch edge or back porch edge by B/F register.
