Ja se nebavim o stovce ale konkretne o STM32F030C6T6
a tam v datasheetu pisou: "Up to two SPIs (18 Mbit/s) with 4 to 16 programmable bit frames". Taktez v Reference manualu je CR2: DS [3:0]: Data size - These bits configure the data length for SPI transfers: 0-2 ~ Not used, 3 ~ 4bit, atd. 15 ~ 16bit. If software attempts to write one of the “Not used” values, they are forced to the value “0111”(8-bit). Dokonce je tam i nejaka ukazka casoveho diagramu pro SPI s 5bit ramci...
