SPI SIGNAL TIMING DESCRIPTION

INTERNAL RESET

The internal SPI status is reset to idle state if one of the following conditions occur:



100ms without receiving data



Reset due to cycling of supply voltage

FILTER CIRCUITRY

Capacitors are added to the following lines in to reduce noise/spikes in order to provide stable SPI

transmission even in EMC affected environment:



CLK



MOSI

A 10nF capacitor is added parallel to ground potential.
