3.10.5.2 VGA Camera Interface
VC_IO_OFF
FILTER_CAM_SYSCLK
The VGA Camera module is connected to main board with 20pin Board to Board connector
(AXK720145). Actually, there is a linking FPCB to connect camera module to the main board.
Its interface is dedicated camera interface port in MSM6275. The camera port supply 24MHz master
clock to camera module and receive 12MHz pixel clock (30fps), vertical sync signal, horizontal sync
signal, reset signal and 8bits data from camera module. The camera module is controlled by I2C port
from MSM6275.
