Electrical Characteristics
4.7.8.5
The IPU Display Interface supports two kinds of display accesses: synchronous and asynchronous. There
are two groups of external interface pins to provide synchronous and asynchronous controls accordantly.
4.7.8.5.1
The synchronous control changes its value as a function of a system or of an external clock. This control
has a permanent period and a permanent wave form.
There are special physical outputs to provide synchronous controls:
The IPU has a system of internal binding counters for internal events (such as HSYNC/VSYCN and so on)
calculation. The internal event (local start point) is synchronized with internal DI_CLK. A suitable control
starts from the local start point with predefined UP and DOWN values to calculate control’s changing
points with half DI_CLK resolution. A full description of the counters system can be found in the IPU
chapter of the i.MX53xD Reference Manual.
4.7.8.5.2
The asynchronous control is a data-oriented signal that changes its value with an output data according to
additional internal flags coming with the data.
There are special physical outputs to provide asynchronous controls, as follows:

The ipp_disp_clk is a dedicated base synchronous signal that is used to generate a base display
(component, pixel) clock for a display.
The ipp_pin_1– ipp_pin_7 are general purpose synchronous pins, that can be used to provide
HSYNC, VSYNC, DRDY or any else independent signal to a display.
The ipp_d0_cs and ipp_d1_cs pins are dedicated to provide chip select signals to two displays.
The ipp_pin_11– ipp_pin_17 are general purpose asynchronous pins, that can be used to provide
WR. RD, RS or any other data oriented signal to display.

Disp1 port has reduced pinout depending on IOMUXC configuration and
therefore may not support all the above configurations. See the IOMUXC
table for details.
The IPU has independent signal generators for asynchronous signals
toggling. When a DI decides to put a new asynchronous data in the bus, a
new internal start (local start point) is generated. The signals generators
calculate predefined UP and DOWN values to change pins states with half
DI_CLK resolution.
