Hello, can anyone know a maximum speed of SPI in slave mode? I think that the max. input (SPI slave) and output (SPI master) clock rate can not be the same, but there is absolutely no information about it in the S3C2440's user manual. /* earlier, for example, i used nxp LPC2478 cpu, and its user manual specified, that maximum SPI clock rate in slave mode, is equal 1/12 of the SPI peripheral clock (1:1 divisor, 72/12=6 MHz). */ Thanks.
