Description
Horizontal Sync Output
A buffered version of VGA horizontal sync can be acquired from this
pin. (Refer to Register 21h, DC register)
Data[11] through Data[0] Inputs
These pins accept the 12 data inputs from a digital video port of a
graphics controller. The levels are 0 to DVDDV, and the VREF
signal is used as the threshold level.
External Clock Inputs
These inputs form a differential clock signal input to the CH7301C
for use with the H, V, DE and D[11:0] data. If differential clocks
are not available, the XCLK* input should be connected to VREF.
The output clocks from this pad cell are able to have their polarities
reversed under the control of the MCP bit (in register 1Ch).
