Note:
Serial Communications Interface
Communications and control of the Z86229 is possible
through a serial control interface. Two Serial Control
Modes are available with the Z86229 performing as a slave
device. These modes are:
1. A two wire, I
2. A three wire, Serial Peripheral Interface (SPI).
A total of five device pins are dedicated to the serial control
port function. These pins are indicated in Table 7.
Programmable Full Screen OSD: 15 display rows by
32 character columns
Graphics characters
Double-High and Double-Wide characters
Fully programmable display positioning (information
may be placed anywhere on the screen)
Accepts externally supplied (or internally generated
VSYNC to enable OSD even when no video is present)
New font with descenders on lower case letters
