41xx fix. funct. SPI slave without SS
I'm trying to implement a slave board with CY8C4125 (so, without UDB) that comunicate with a master board trough SPI. Obviously the PSoC4 is SPI slave. The master doesn't manage the SS signal ('cause it's a point-to-point connection with only one slave). The SCB block configured as SPI Slave needs it so I've tryed the Unconfigured mode with routed only MISO, MOSI and SCLK signals but it seems doesn't receive any packet from master.
Is the SS signal fundamental so I must manage it or there are any workaround ?
Thanks for replies
