I am using a PSoc5 device and need a 3V SPI bus and a 5V SPI bus. Would the following work?
Use 2 X SPI Master components, one for the 3V bus and the other for the 5V bus. Then connect the mosi and miso pins of the one master to one port and connect the VDDIO of that port to 3V and then connect the mosi and miso pins of the second master to another port and connect the VDDIO of the second port to 5V.
I apologise if this question has already been answered somewhere else.
