We are going to develop a fault diagnosis tester for Electric Vehicles，which the main function is to achieve diagnosis on online. And we have designed the PCB by ourself with the SPC5606S core. Something has been toubled me for a long time , we are not clear about the Parallel Data Interface (PDI) . Just as the reference mannual says" The PDI input is directly injected into the DCU background plane FIFO ". So I am wonder the function of the PDI for LCD display module.
Waiting for your answers!
