FEATURES

GENERAL DESCRIPTION

The Z90349 and Z90348 are ROMless versions of the

Z89300 family of Zilog's Digital Television Controllers

designed for use in emulators and development boards to

provide complete audio and video control of television

receivers, video recorders, and advanced on-screen

display facilities.

The powerful Z89C00 RISC processor core allows users to

control on-board peripheral functions and registers using

the standard processor instruction set.

In closed caption mode, text can be decoded directly from

the composite video signal and displayed on the screen

with assistance from the processor's digital signal

processing capabilities. The character representation in

this mode allows for a simple attribute control through the

insertion of control characters.

The character control mode provides access to the full set

of attribute controls. The modification of attributes is allowed

on a character-by-character basis. The insertion of control

characters permits direction of other character attributes.

Display attributes, including underlining, italics, blinking,

eight foreground/background colors, character position

offset delay, and background transparency, are made

possible through a fully customized 512 character set.

DIGITAL TELEVISION CONTROLLER

IN-CIRCUIT EMULATOR (ICE) DEVICE

Serial interfacing with the television tuner is provided

through the tuner serial port. Digital channel tuning

adjustments may be accessed through the industry-

standard I

Additional hardware provides the capability to display two

to three times normal size characters. The smoothing logic

contained in the on-screen display circuit improves the

appearance of larger fonts. Special circuitry can be

activated to improve the visibility of text by adding a right-

sided shadow effect to the characters.

Receiver functions such as color and volume can be

directly controlled by six 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).
