4.4 Using Software Driver
Some motherboards, by request, are supplied with application code already preloaded to
configure and run the ADV7604. The following explains the behaviour of the
motherboard interfaces when the application is running
LEDS

D2 and D4 are on

D5 flashes during loading of FPGA

D6, D7, D15 and D16 are on
MB_EN switch

Driver disabled with switch at position 0. ATV Benchtop may be used.

Driver enabled with switch at position 1. ATV Benchtop may not be used.
Push buttons

FPGA_RESET resets the FPGA and reloads the firmware

S2 S7 are not used

S9 resets the ADV7604 evaluation board with no handshaking to the application.
If this button is pressed, hot plug must be reasserted.
Serial interface

If a suitable serial terminal application is connected to the serial port of the ATV
motherboard (settings: 115200, 8 bit, none, 1, no flow control) the application
provides event and debug messages and allows I2C read and write commands.
