In particular, owing to the built-in SYNC-SEP (synchronous separation) 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 suitable for AV systems such as VTRs, LDs, and so on. It is a silicon gate CMOS process and M35052-XXXSP is housed in a 20-pin shrink DIP package, M35052-XXXFP is housed in a 20-pin shrink SOP package. For M35052-001SP/FP that is a standard ROM version of M35052XXXSP/FP respectively, the character pattern is also mentioned. 17 ← → ← 14 8 13 9 12 10 11 Outline 20P2Q-A CP2 OSCIN VSS 16 15 HOR → → P1 P0 TEST B → EDO VSS MITSUBISHI MICROCOMPUTERS M35052-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS PIN DESCRIPTION Symbol OSC1 Clock input TESTA Test pin __ Input/ Output Input — Function This is the filter output pin 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.

Edge sway Fig. 17 Example of display b) If what display exceeds the display area in dealing with external synchronization, (if use double - size characters), set the character code of the addresses lying outside that display area blank code – “FF16”.

Fig. 18 Example of display 27 MITSUBISHI MICROCOMPUTERS M35052-XXXSP/FP SCREEN CHARACTER and PATTERN DISPLAY CONTROLLERS (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) Power supply noise When power supply noise is generated, the internal oscillator circuit does not stabilize, whereby causing horizontal jitters across the picture display. Therefore, connect a bypass capacitor between 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, MPAL 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 conditions. 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 synchronization with the subcarrier and phase. Consequently, this results in color flicker and lost synchronization 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 (address 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. 28 3) Wait 20 ms (the period necessary for the internal oscillation circuit to stabilize) before entering data. 4) Set necessary data in other registers, and make the display RAM ready.

The timing about power supplying of AC pin is shown in Figure 20. tW is the interval after the supply voltage becomes 0.8 ✕ VDD or more and before the supply voltage to __ __ the AC pin (VAC) becomes 0.2 ✕ VDD or more. After supplying the power (VDD and VSS) to M35052-XXXSP/FP, the tW time must be reserved for 1ms or more.
