The SCREEN_WIDTH, SCREEN_HEIGHT, H_SYNC_WIDTH, V_SYNC_WIDTH, BGXP, BGYP and
V_SYNC_WIDTH_L parameters are programmed via the SDC_HOR_CONF, SDC_VER_CONF,
SDC_BG_POS Registers. The FW and FH parameters are programmed for the corresponding DMA
channel. The DISP3_IF_CLK_PER_WR, HSP_CLK_PERIOD and DISP3_IF_CLK_CNT_D parameters
are programmed via the DI_DISP3_TIME_CONF, DI_HSP_CLK_PER and DI_DISP_ACC_CC
Registers.

DI_DISP3_TIME_CONF Register.

Parameter
HSP_CLK is the High-Speed Port Clock, which is the input to the Image
Processing Unit (IPU). Its frequency is controlled by the Clock Control
Module (CCM) settings. The HSP_CLK frequency must be greater than or
equal to the AHB clock frequency.
