Directly Controlled Receiver Functions
The Z89314/318 are members of Zilog's family of Digital
Television Controllers designed 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 include underlining, italics, blinking,
eight foreground/background colors, character position
offset delay, and background transparency are made
possible through a fully customized 512 character set,
formatted in two 256 character banks.
GENERAL DESCRIPTION
Serial interfacing with the television tuner is provided
through the tuner serial port. This version of the Z89300
series does not offer I
2
C capability
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. Fringing circuitry can be
activated to improve the visibiity of text by surrounding the
character lines with a one-pixel border.
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).
