GENERAL DESCRIPTION
The Z89302/04/06 Digital Television Controllers are
designed to provide complete audio and video control of
television receivers, video recorders, and advanced on-
screen display facilities. The Television Controllers feature
a Z89C00 RISC processor core that controls the 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.
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 tuning 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.
The Z89302/04/06 has two internal 12 MHz VCOs that are
referenced to a 32 kHz internal oscillator to provide the
system clock. In Sleep Mode, the controller uses the
32 kHz clock for the system clock to reduce power
consumption. The processor can be suspended by placing
it into STOP Mode when main power is not available for
low-power consumption.
