SPI Library using Serial Port B collides with PB0 Serial flash SCLK?

Question

Using Serial Port B with the SPI library sets the SCLK on PB0. The RCM56XXW.lib lists that as the Serial Flash SCLK.
Will using PB0 for an external SPI device cause an issue with the Serial Flash?

Answer 1

When choosing I/O, I recommend that you should pay close attention to any helpful text in Table 2’s Notes column. For instance, the notes for PB0 (edge connector pin 27) explain that PB0 is used for communicating with the serial flash and for WiFi signal strength detection; therefore, a custom application would require very careful programming in order to avoid interfering with these other uses.
