GENERAL DESCRIPTION

The Z89300/01 Digital Television Controller is an application- specific controller designed to provide complete audio and video control of television receivers, video recorders, and advanced on-screen display facilities. The Z89301 is the one-time-programmable (OTP) version of the Z89300.The powerful 12 MHz Z89C00 RISC processor core allows the user to control the on-board peripheral functions and registers using the standard processor instruction set.

The extensive character attributes can be controlled in two modes: by the on-screen display controller character control mode for maximum display control flexibility, and closed caption mode for optimum display of closed caption text.

Closed caption text can be decoded directly from the composite video signal with the assistance of the processors digital signal processing capabilities and displayed on the screen. The character representation in this mode allows for a simple attribute control through the insertion of control characters, and each word of RAM specifies two displayed characters.
