Connection Topology of 6-Wire SPI and HostThe product includes a connection topology for the 6-wire SPI interface and host.
Timing Diagram of Host Sending Commands (CMD) to Module
● The host sets SS to the active state.
● The host checks whether there is an INT request during this period.
● If there is an INT request, the host postpones sending the command and receives a notification from the module.
● The module prepares the SPI peripheral for subsequent operations.
● The module activates RDY to notify the host that data transmission can start.
● After data transmission is completed, the host deactivates SS.
● The module waits for SS to be deactivated.
● The module ends receiving and deactivates RDY.
Timing Diagram of Module Sending Responses (RSP) and Notifications (NTF) to Host
● The module prepares SPI and pushes INT to the active state.
● The host is triggered when INT is activated.
● The module waits for SS to be activated.
● The host sets SS to the active state and performs SPI transmission.
● To determine the response length, the host can first receive the first four bytes containing the UCI header and length information.
● The host can then read the remaining bytes.
● The host shall not revoke SS between the two SPI transmissions.
● Alternatively, the host can transmit the maximum UCI packet length.
● Once the SS line is activated, the module takes the data as subsequent SPI transmissions and ignores the incoming data.
● When data transmission is completed, the INT line is deactivated.
● The host waits for the INT line to be deactivated before releasing the SS line to avoid a race condition.
