GENERAL DESCRIPTION

The Z89332 Digital Television Controller is designed to
provide complete audio and video control of television re­ceivers, video recorders, and advanced on-screen display
facilities. The television controller features a Z89C00 RISC
processor core that controls the on-board peripheral func­tions and registers using the standard processor instruc­tion set.

Character attributes can be controlled through two modes:
the on-screen display Character-Control Mode and the
Closed-Caption Mode. The Character-Control Mode pro­vides access to the full set of attribute controls, allowing the
modification of attributes on a character-by-character ba­sis. The insertion of control characters permits direction of
other character attributes. Closed-caption text can be de­coded directly from the composite video signal and dis­played on-screen with the assistance of the processor's
digital signal processing (DSP) capabilities.

The fully customized 512 character set, formatted in two
256 character banks, can be displayed with a host of dis­play attributes that include underlining, italics, blinking,
eight foreground/background colors, character position off­set delay, and background transparency.

Speed: 12 MHz

Serial interfacing with the television tuner is provided
through the tuner serial port. Other serial devices, such as
digital channel tunning adjustments, may be accessed
through the industry-standard I

User control can be monitored through the keypad scan­ning port, or the 16-bit remote control capture register. Re­ceiver functions such as color and volume can be directly
controlled by eight 8-bit pulse width modulated ports.

Notes:

All Signals with a preceding front slash, "/", are active Low,
e.g.: B//W (WORD is active Low); /B/W (BYTE is active
Low, only).
