5.6. Pin descriptions
5.6.1. Connector X2004 ( VGA / Sound )
BCKBAT+
3V backup cell input. BATT should be connected to a 3V backup cell for RTC operation and storage
register non-volatility in the absence of system power. (typ. VBATT = 3V to 3.3V)
VGA_HS
Horizontal Sync: This output supplies the horizontal synchronization pulse to the monitor. It is normally
not needed for flat panels (TTL).
VGA_VS
Vertical Sync: This output supplies the vertical synchronization pulse to the monitor. It is normally not
needed for flat panels (TTL).
