GENERAL DESCRIPTION
The Z89332 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.
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.
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.
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
2
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.
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 be-
