Abstract:
A SPI master may configure a set of hardware registers associated with a SPI client with a set of communication parameters. The SPI master may send a message to the SPI client. The SPI master may periodically ping the SPI client until the SPI master receives an acknowledgement message from the SPI client in response to the message from the SPI master. The SPI master may periodically ping the SPI client based upon the set of communication parameters. The SPI client may transmit the acknowledgement message to the SPI master based upon the set of communication parameters. The SPI master may receive the acknowledgement message from the SPI client. The SPI master may determine a status of a read operation or a write operation associated with the message based upon the acknowledgement message.
