Hello, I have a question about the CLK - signal / CLK - Pin by SPI interface. I use the SPI interface as a master in Mode 0, when the SPI interface is not use (standby) the level of the CLK - signal is low. Is it possible to set the CLK - signal to high, when the SPI interface ist not use (standby) ?

Thanks !
