Abstract:
A synchronous serial peripheral device has a transmission unit coupled with a data output line and a clock unit coupled with a clock line. The serial peripheral device transmits a minimum of a single transmission, wherein in a first operating mode the transmission unit and the clock unit are configurable to perform a data transmission with a data length that can be defined to be between one (1) and eight (8) bit.
Abstract:
A serial peripheral interface (SPI) module, comprising a transceiver, the transceiver including a clock line, a data line and at least one slave select line. The SPI also comprises an interface circuit configured to operate in an automatic slave select mode, wherein the interface circuit is configured to automatically assert the slave select line at least one clock before a first clock edge is generated.
Abstract:
A serial peripheral interface (SPI) module includes a transceiver including a clock line, a data line and at least one slave select line. The module also includes an interface circuit configured to monitor the slave select line and assert a fault based upon an incorrect de-assertion of the slave select line.
