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.
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 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).
Power connections follow conventional descriptions below:
