Note:
PWM 6 can be either a 6-bit or 14-bit output.
The Z90255 takes full advantage of Zilog’s Z8 expanded register file space to offer greater
flexibility in creating a user-friendly On-Screen Display (OSD).
Three basic addressing spaces are available: Program memory, Video RAM (VRAM) and
the Register file. The register file is composed of 300 bytes of general-purpose registers,
16 control and status registers, one I/O port register and three reserved registers.
The OSD module supports 10 rows by 24 columns of characters. Each character color can
be specified. There are eight foreground colors and eight background colors. When the
foreground and background colors are the same, the background is transparent.
