General Information
• NCS: Select input, active low
• SCK: Clock input. Data bits on SDI are read at rising SCK edges and written out on
SDO at falling SCK edges.
• SDI: Data input
• SDO: Data output
Level definition:
logic 0 = low voltage level
logic 1 = high voltage level
Note: It is possible to send multiple frames while the device is selected. It is also possible
to change the access mode while the device is selected by sending a different
instruction.
Note: In all bus transfers MSB is sent first, except the received data read out from the
FIFO. There the bit order is given as first bit that is received is also the first bit that is
transferred via the bus.
