The PCLK frequency for each LCD output is derived from a dedicated input clock: LCD1_CLK, LCD2_CLK, or LCD3_CLK for the three LCD outputs, respectively. Each input clock is divided by the values of the DISPC_DIVISORo[23:16] LCD bit field and then the DISPC_DIVISORo[7:0] PCD bit field independently for each LCD pixel clock (see Figure 11-43). DSS_DISPC_LCD1_PCLK, DSS_DISPC_LCD2_PCLK, and DSS_DISPC_LCD3_PCLK are independent:
The functional clock of the DISPC is derived from F_CLK by an independent divisor. The dividing value is set in the DISPC_DIVISORo[23:16] LCD bit field.
For backward compatibility, the divisor value LCD can be set to the value of LCD1. To enable this functionality, the DISPC_DIVISOR[0] ENABLE bit must be set to 1.
