FUNCTIONAL DESCRIPTION
The W82C610 converts analog video signals to digital data and detects the
SoftControl
signature
code. If the signature code is detected, the W82C610 informs the microcontroller and places the
SoftControl
data on the parallel bus.
SoftControl
allows the PC to communicate with the monitor over the normal video cable. No
additional circuits are required in the PC. Communication is accomplished by means of coded data
transferred on the RGB video signals by the
SoftControl
program. To prevent false readings, data are
sent with a 12-bit signature code.
The W82C610 provides a data path for inputs from key pad to microcontroller. Output ODB0-ODB3
can be either from key pad (IDB0
IDB3) or from VGA cable (RDATA, GDATA, BDATA).
