SPRUJ10D May 2022 – September 2023
The AM263x LauncPad maps two SPI instances (SPI0,SPI1) from the AM263x SoC to the BoosterPack Headers. Series termination resistors are placed near the SoC for each SPI clock and SPI D0 signal. There is a 2:1 Mux (SN74CB3Q3257PWR) that is responsible for selecting SPI signals for proper function. The Mux is driven by two GPIO signals that are generated from the AM263x SoC.
Output Enable (OE) | Select (S) | Input/Output | Function |
---|---|---|---|
Low | Low | A ↔ B1 | A port = B1 port |
Low | High | A ↔ B2 | A port = B2 port |
High | X | Hi-Z | Disconnect |
