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).
