MICROWIRE

A serial signal format developed by National Semiconductor; the hardware structure and signal operation are the same as SPI (Serial Peripheral Interface). The line structure includes device selection (CS: Chip Select), clock (SK: Serial Clock), and data input/output (DI: Data Input / DO: Data Output).

Wrong CS/CLK/DI/DO, Chip Select Edge, or Data Edge yields incorrect decode. For channel-prefix differences, see Settings.
