MB90097
DESCRIPTION
MB90097 on-screen display controller displaying text graphics screen. Since three-channel output control function, small package, voltage requirement operation, suitable on-screen display video equipment such camera-integrated VTRs. MB90097 provides display screen made characters lines, capable displaying different characters each consisting dots. display functions MB90097 includes wealth character qualifying functions such character background shading (shadow casting) individual character size setting, supporting 16-color display each character. They also include line background, screen background, sprite character display functions, enabling screen displayed variety configurations. integrated font contains different character patterns which user.

Notes Issuing Commands
This section summarizes notes issuing commands. Initialization MB90097 enters display-off state (*1) upon reset input (input LOW-level signal RESET pin). contents VRAM (character line RAM) initialized then (undefined immediately after power supply turned on). When MB90097 released from reset input, issue following commands initialize control operation: clock control (Command 11-2) control (Command 13-0) After that, other command data contents VRAM. (VRAM setting requires normal clock sync signal inputs.) reset input initializes control bits shown below Screen output control (command 5-00) Sprite Screen background Character, character background, line background Sets VC0, VC1, VC2, pins positive logic output.

Command refresh Command data MB90097 contents internal VRAM remain held long MB90097 powered. serial control, sync, clock signals affected external noise, however, they become abnormal signals, preventing internal registers VRAM from being normally. should therefore refresh command data VRAM data periodically restore them from abnormal state. Command issuance timing When VRAM write command, such character data setting line control data setting command, other control command issued, command executed immediately, reflecting result (command setting) screen. When such command issued during display period, display relevant field involve transient distortion. prevent this, should issue command during vertical blanking interval. Also, restriction internal circuit configuration cause deviation display position first display field when DSP, SDS, control command 5-00 (screen output control from prevent this, should issue command 5-00 within period after leading edge sync signal.

Line Background Display Line background display line displays line background line area characters line, areas right left that area, line spacing areas above below There four types line backgrounds available (None, Solid fill, Concaved shaded background, Convexed shaded background), which each line. Shaded line background display used display shaded background frame highlight color shaded background frame shadow color above below line background area, respectively, along with line background color display. Line background control (Setting each line) Line control data setting (Command Bits Line background background (undisplay) Solid-filled background Concaved, shaded background Convexed, shaded background Line background color (Setting each line, selected from among colors) Line control data setting (Command Bits Shaded background highlight color (Setting each screen, selected from among colors) Shaded background frame color control (Command 6-1) Bits Shaded background shadow color (Setting each screen, selected from among colors) Shaded background frame color control (Command 6-1) Bits

Shaded Background Succeeding Line Merge Display Specifying "shaded background succeeding line merge display" line enables line displayed with line background merged with that next line. This undisplays lower line line background shadow frame current line upper line line background shadow frame next line, allowing more lines displayed with shaded line backgrounds. Shaded background succeeding line merge control (Setting each line) Line control data setting (Command Shaded background succeeding line merge control
Examples shaded background succeeding line merge display
(Shaded background frame highlight color) Convexed, shaded background with succeeding line merge Convexed, shaded background with succeeding line merge (Shaded background frame shadow color)

Note: Specifying shaded background succeeding line merge display applies merge control character line backgrounds same time. character background extended display line, however, merge control ignores shaded background characters that line.
