GENERAL DESCRIPTION
The Z89331 One-Time Programmable (OTP) Digital
Television Controller is designed to provide complete
audio and video control of television receivers, video
recorders, and advanced on-screen display facilities. The
Z89331 features a Z89C00 RISC processor core that
controls 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.
CP95TEL1400 11/95
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 I2C port.
User control can be monitored through the keypad
port, or the 16-bit remote control capture register.
functions such as color and volume can be
controlled by eight 8-bit pulse width modulated
scanning

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).
