5.10.6.4 DSS

Two Display Parallel Interfaces (DPI) channels are available in DSS named DPI Video Output 2 and DPI Video Output 3.

NOTE

The DPI Video Output i (i = 2, 3) interface is also referred to as VOUTi.

Every VOUT interface consists of:

  • 24-bit data bus (data[23:0])
  • Horizontal synchronization signal (HSYNC)
  • Vertical synchronization signal (VSYNC)
  • Data enable (DE)
  • Field ID (FID)
  • Pixel clock (CLK)

NOTE

For more information, see the Display Subsystem chapter of the Device TRM.

CAUTION

The I/O Timings provided in this section are valid only if signals within a single IOSET are used. The IOSETs are defined in Table 5-43.

CAUTION

The I/O Timings provided in this section are valid only for some DSS usage modes when the corresponding Virtual I/O Timings or Manual I/O Timings are configured as described in the tables found in this section.

CAUTION

All pads/balls configured as vouti_* signals must be programmed to use slow slew rate by setting the corresponding CTRL_CORE_PAD_*[SLEWCONTROL] register field to SLOW (0b1).

Table 5-39, Table 5-40 through Table 5-42 assume testing over the recommended operating conditions and electrical characteristic conditions.

To configure the desired virtual mode the user must set MODESELECT bit and DELAYMODE bitfield for each corresponding pad control register.

The pad control registers are presented in Table 4-32 and described in Device TRM, Control Module Chapter.

Virtual IO Timings Modes must be used to ensure some IO timings for VOUT3. See Table 5-29Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 5-44Virtual Functions Mapping for VOUT3 for a definition of the Virtual modes.

NOTE

To configure the desired Manual IO Timing Mode the user must follow the steps described in section "Manual IO Timing Modes" of the Device TRM.

The associated registers to configure are listed in the CFG REGISTER column. For more information please see the Control Module Chapter in the Device TRM.

Manual IO Timings Modes must be used to ensure some IO timings for VOUT2. See Table 5-29, Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-45, Manual Functions Mapping for DSS VOUT2 IOSET1 for a definition of the Manual modes.

Manual IO Timings Modes must be used to ensure some IO timings for VOUT3. See Table 5-29, Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-46, Manual Functions Mapping for DSS VOUT3 for a definition of the Manual modes.

Table 5-46 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
