Does anybody know the state of DAI/DPI pins after reset? Is it input or output or three-state? thanks!
DAI/DPI pins are bi-directional and pulled up on reset. Depending on the way you program your peripheral it becomes input/output/tristate.
For example if you choose for an SPI master boot then SPICLK/MOSI bits are driven while the SPIDS pin is tri-stated.
Hope this helps
thanks for your reply. I was confused that in 21369 data sheet, it says that after reset the DAI/DPI pins is pulled high,while in SHARC21469 data sheet, it says that after reset, DAI/DPI pins is High-Z.
