WebJul 9, 2024 · The the master will tri-state the data pin and clock data back from the slave. When sending data the RXDATA registers of the master will normally shift in the data sent. As this data is normally not interesting we can block the receiver while sending data by writing a 1 to RXBLOCKEN in USARTn->CMD. WebThe SPI bus is in one of the states listed in spi_transfer_status_t. The bus state is used by the exchange one byte function: This function will wait until the SPI bus is no longer BUSY before exchanging a byte. This allows the exchange byte function to work seamlessly with the exchange, receive and transmit block functions. cpi perth 2021
