See Table 5 for the GPIOs used on the Parallel display interface and a description of their function. This

table does not include the 28 parallel display signals (DATA[23:0], PCLK, VSYNC, HSYNC, and DE).

NOTE: no configuration changes are required to switch between usage of the onboard DVI connector or

an external display plugged into the display expansion connectors.

OMAP4460 Pandaboard ES

System Reference Manual

Signal Name

TFP410 Device Power down (note: this GPIO goes through a voltage

H_GPIO_0/

translator to meet the 3.3V I/O requirement of the TFP410 on this pin)

TFP410_NPD

1 = Normal Operation, 0 = Power Down

TFP410 Monitor Sense

0 = Powered on receiver sensed at the differential outputs

DVI_MSEN

1 = No powered on receiver detected. (note: this output from the

TFP410 is open-drain and has a pull-up to 1.8V, so it is connected

directly to OMAP)
