DIVE[1:0]: Sets the division ratio of DOTCLK. The R61509V’s internal operation is synchronized with the frequency-divided DOTCLK, the frequency of which is divided by the division ratio set by DIVE[1:0]. This setting is enabled while the R61509V’s display operation is synchronized with RGB interface signals.

Table 31 Division Ratio of DOTCLK (RGB interface operation)

DIVE[1:0]Division ratio

2’h0	1/1
2’h1	1/2
2’h2	1/4
2’h3	1/8

Note: Clock frequency for internal operation = DOTCLK / (( DIVE x (PCDIVL + PCDIVH) ). For details, see R014h.
