The serial peripheral interface (SPI) allows an external microcontroller (Master) to AMIS−30512. The implemented SPI block is designed to interface directly with numerous micro−controllers from several manufacturers. AMIS−30512 acts always as a Slave and can’t initiate any transmission. The operation ...
