Reversal of the U and V timing using the H / L state of TEST[2] can be controlled regardless of whether CLKSW is
HIGH or LOW (the input clock is a doubled clock or not).
When using the RGB input mode, TEST[2] should be fixed at LOW.
In the Master mode, HSYNC is output at the timing shown in Fig. 26. For that reason, the timing of U and V should
be determined by counting from that falling edge. In the Slave mode, the HSY, U, and V data should be input at the
timing shown in Fig. 26.

In a doubled clock mode, the timing of U and V is as shown in Fig. 7-1.
In a regular clock mode, the timing of U and V is as shown in Fig. 7-1.
In a doubled clock mode, the timing of U and V is as shown in Fig. 7-2.
In a regular clock mode, the timing of U and V is as shown in Fig. 7-2.
