Product Features
Connection Topology Description of Module 6 - wire SPI and host
Timing Diagram of Host Sending Commands (CMD) to Module
The following order should be followed:
- The host sets SS to the active state.
- The host should check whether there is an INT request during this period.
- If there is an INT request during this period, the host should postpone sending the command and receive 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 the 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 following order should be followed:
- 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.
- In order to determine the length of the response, the host can first receive the first four bytes including the UCI header and length information.
- Then the host can read the remaining bytes.
- The host shall not revoke SS between two SPI transmissions.
- Or, 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 the data transmission is completed, the INT line is deactivated.
- The host should wait for the INT line to be deactivated before releasing the SS line to avoid a race condition.
