SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
DESCRIPTION
PIN CONFIGURATION (TOP VIEW)
The M35052-XXXSP/FP is TV screen display control IC which can
be used to display information such as number of channels, the date
and messages and program schedules on the TV screen.
In particular, owing to the built-in SYNC-SEP (synchronous separa-
tion) circuit, the synchronous correction circuit, the Decoder circuit,
and to the Encoder circuit, external circuits can be decrease and
character turbulence that occurs when superimposing can be reduced.
The processor can conform to the EDS broadcast service and is suit-
able for AV systems such as VTRs, LDs, and so on.

MEMORY CONSTITUTION
Address 0016 to EF16 are assigned to the display RAM, address F016
to F816 are assigned to the display control registers.
The internal circuit is reset and all display control registers (address
F016 to F816) are set to “0” and display RAM (address 0016 to EF16)
are RAM erased when the AC pin level is “L”.
Set “0” in any of DA7, DAD through DAF of addresses 0016 through
EF16, and of DAE and DAF of addresses F016 through F816.
Setting the blank code “FF16” as a character code is an exception.
TESTn (n : a number) is MITSUBISHI test memory, so be sure to
observe the setting conditions.

Notes 1. In dealing with the internal synchronization, cut off external video signals outside the IC. The leakage of external input video signals
can be avoided.
Notes 2. In displaying color superimposition, enter into the OSCIN pin the fSC signal that phase-synchronizes with the color burst of the
composite video signals (input to the CVIN pin).
Notes 3. Erases all the display RAM. The character code turns to blank-FF16, the encode data bit and the blinking bit turn to “1” respectively,
and reversed character bit turns to “0”.

Supplemental explanation about display control register
(1) How to effect synchronous separation from composite video signals
Synchronous separation is effected as follows depending on the width of L-level of the vertical synchronous period.
1. Less than 8.4 ˚s ······ Not to be determined to be a vertical synchronous signal.
2. Equal to or higher than 8.4 ˚s but less than 15.6 ˚s ······ When two clocks continue, if take place, it is “L” period is determined to be a
vertical synchronization signal.
3. Equal to or higher than 15.6 ˚s ······ It is “L” period is determined to be a vertical synchronous signal with no condition.
The determination is made at the timing indicated by V in Fig.3 either in case 2 or in case 3.

Using area for encode data setting
Useless area
Start setting data from the first line. Data set in the lines specified by registers EVP0 through EVP3 (address F216) will be
encoded.
Setting data in the second and subsequent lines, it is possible to set encode data to ten consecutive lines from those secified
by registers EVP0 to EVP2.
Similarly to encode line N specified by registers EVP0 through EVP2, extending encode lines to line N-1 and to line N+1, it is
possible to read encode data more certainly.

SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS
CHARACTER FONT
Images are composed on a 12 ✕ 18 dot matrix, and characters can
be linked vertically and horizontally with other characters to allow the
display the continuous symbols.
Character code “FF16” is so fixed as to be blank and to have no
background, thus cannot assign a character font to this code.
(1) Border display (set by register BLK0, 1 (address F816))
12 dots
When the character extends to the
top dot of the matrix, no border is
left at the top.
When the character extends to
the bottom (18th) dot of the matrix,
no border is left at the bottom.
Note: Hatching represents border.
(2) Cursor display (Border display)

at the bottom (18th) dot, no

Precautions
(1) Points to note in setting the display RAMs
a) Be careful to the edges may sway depending on the combina-
tion of character’s background color and raster color.
Edge sway
Fig. 17 Example of display
b) If what display exceeds the display area in dealing with exter-
nal synchronization, (if use double - size characters), set the
character code of the addresses lying outside that display area
blank code – “FF16”.

(2) Before setting registers at the starting of system, be sure to reset
the M35052-XXXSP/FP by applying “L” level to the AC pin.
3) Wait 20 ms (the period necessary for the internal oscillation cir-
cuit to stabilize) before entering data.
4) Set necessary data in other registers, and make the display RAM
ready.
(3) Power supply noise
When power supply noise is generated, the internal oscillator cir-
cuit does not stabilize, whereby causing horizontal jitters across
the picture display. Therefore, connect a bypass capacitor be-
tween the power supply and GND.
(4) Synchronous correction action
When switching channel or in the special playback mode (quick
playback, rewinding, and so on) of VTR, effect of synchronous
correction becomes strong, and distortion of a character is apt to
occur because the continuity of video signal is suddenly switched.
When the continuity of video signal is out of order, erasure of
displayed characters is recommended in a extreme short time to
raise the quality of displayed characters.
(5) Notes on fSC signal input
This IC amplifies the subcarrier frequency (fSC) signal (NTSC, M-
PAL system: 3.58MHz, PAL system: 4.43MHz) input to the OSCIN
pin (17-pin) and generates the composite video signal internally.
The amplified fSC signal can be destabilized in the following cases.
a) When the fSC signal is outside of recommended operating con-
ditions.
b) When the waveform of the fSC signal is distorted.
c) When DC level in the fSC waveform fluctuates.
When the amplified signal is unstable, the composite video
signal generated inside the IC is also unstable in terms of syn-
chronization with the subcarrier and phase.
Consequently, this results in color flicker and lost synchroniza-
tion when the composite video signal is generated. Make note
of the fact that this may prevent a stable blue background from
being formed.
(6) Forbidding to stop entering the fSC signal
This IC doesn’t properly work if the fSC signal is not entered into
the OSCIN pin (pin 17), so don’t stop the fSC signal so as to work
the IC. To stop the IC, turn the display off (set 0 in the register
DSPON (address F816).)
(7) Forbidding to set data during the period in which the internal
oscillation circuit stabilizes
a) To start entering the fSC signal when its input is stopped.
b) To start oscillating the oscillation circuit for display when its
oscillation is stopped. (to assign “1” to the register STOP1 (ad-
dress F816) when it is assigned “0”, or the like.)
c) To turn on the internal bias when it is turned off. (to assign “1”
to the register LEVEL1 (address F816) when it is assigned “0”.)
There can be instances in which data are not properly set in the
registers until the internal oscillation circuit stabilizes, so follow
the steps in sequence as given below.
1) Set “0” in the register DSPON (address F816). (the display is turned
off)
2) Effect the settings a), b), and c) given above.
