The VP output can be programmed to operate in Stall Mode, where there is a stall handshake mechanism (back-pressure) with the display peripheral to which the VP is connected. No sync signals (HS, VS) are generated in Stall Mode of operation. Data and Enable (DE) signals are provided only when the stall signal is de-asserted (1’b0) by the peripheral. The Stall Mode can be enabled via the DSS0_VP_CONTROL[11] STALLMODE register bit.
In this SoC, the Stall Mode of operation is supported only on the VP outputs connected to the DSI peripheral module.
There are two types of data transfer, if Stall Mode is enabled, that can be selected by the DSS0_VP_CONTROL[12] STALLMODETYPE register bit:
