Equation 1
Table 44-12. Minimum LCDDOTCK Period in LCDC Core Clock Cycles
The LCDDEN signal indicates valid data in the LCD Interface.
After each horizontal line of data has been shifted into the LCD, the LCDHSYNC is asserted to
cause the line to be displayed on the panel.
The following timing parameters can be configured:
There is a limitation in the minimum values of VHDLY, HPW and HBP parameters imposed by
the initial latency of the datapath. The total delay in LCDC clock cycles must be higher than or
equal to the latency column in
