2.4.11
An 8-bit VGA pixel port is provided to support basic VGA modes. It is latched on the rising edge of CLK0.
In this mode RCLK equals the dot clock. It is assumed that, in most BT485 designs, the PSEL input is tied
high and software is used to switch modes. Therefore, the PSEL input performs no function in the BT485
mode of the TVP3025 and the VGA mode is enabled by setting CR25 in command register 2 to logic 0. For
modes other than VGA, CR25 needs to be set to a logic 1.

32 cursor mode or cursor color 3. The pattern for the cursor is provided by the cursor RAM, which can
be accessed by the MPU at any time. The cursor is positioned through the cursor-position (x, y) registers
(see Figure 2–18). Writing (0, 0) to the cursor-position registers places the cursor off the screen.
Writing (1, 1) to the cursor-position registers places the lower right pixel of the cursor array on the upper left
corner of the screen. Only one cursor pattern per frame is displayed at the location specified, regardless
of the number of updates to (x, y). The vertical or horizontal location of the cursor is not affected during any
frame display. There are no restrictions on updating (x, y) other than both the cursor-position registers must
