GENERAL DESCRIPTION

The Z90365 Digital Television Controller is designed to

provide complete audio and video control of television re-

ceivers, video recorders, and advanced on-screen display

facilities. The television controller features a Z89C00 RISC

processor core that controls the on-board peripheral func-

tions and registers using the standard processor instruc-

tion set.

Serial interfacing with the television tuner is provided

through the tuner serial port. Other serial devices, such as

digital channel tuning adjustments, may be accessed

through the industry-standard I C port.

User control can be monitored through the keypad scan-

ning port, or the 16-bit remote control capture register. Re-

ceiver functions such as color and volume can be directly

controlled by eight 8-bit pulse width modulated ports.

Character attributes can be controlled through two modes:

the on-screen display Character-Control Mode and the

Closed-Caption Mode. The Character-Control Mode pro-

vides access to the full set of attribute controls, allowing the

modification of attributes on a character-by-character ba-

sis. The insertion of control characters permits direction of

other character attributes. Closed-caption text can be de-

coded directly from the composite video signal and dis-

played on-screen with the assistance of the processor's

digital signal processing (DSP) capabilities.

Notes: All Signals with a preceding front slash, "/", are

active Low. For example, B//W (WORD is active Low);

/B/W (BYTE is active Low, only).

Power connections follow conventional descriptions be-

low:

The fully customized 512 character set, formatted in two

256 character banks, can be displayed with a host of dis-

play attributes that include underlining, italics, blinking,

eight foreground/background colors, character position off-

set delay, and background transparency.
