The port is a four wire serial port. The host micro-controller always initiates communication; the ADNS-3050 never initiates data transfers. SCLK, MOSI, and NCS may be driven directly by a micro-controller. The port pins may be shared with other SPI slave devices. When the NCS pin is high, the inputs are ignored and the output is at tri-state. The lines that comprise the SPI port: SCLK: Clock input. It is always generated by the master (the micro-controller). MOSI: Input data. (Master Out/Slave In) MISO: Output data. (Master In/Slave Out) NCS: Chip select input (active low). NCS needs to be low to activate the serial port; otherwise, MISO will be high Z, and MOSI & SCLK will be ignored. NCS can also be used to reset the serial port in case of an error. Chip Select Operation The serial port is activated after NCS goes low; otherwise, MISO will be high-Z, while MOSI and SCLK will be ignored. If NCS is raised during a transaction, the entire transaction is aborted and the serial port will be reset. This is true for all transactions. After a transaction is aborted, the nor- mal address-to-data or transaction-to-transaction delay is still required before beginning the next transaction. To improve communication reliability, all serial transactions should be framed by NCS. NCS can also be used to reset the serial port in case of an error occurs. |
