Re: dsPIC33CK256M508 family SPI SSx pins not labeled
There is no hard pin mapping for SPI1 or 3.
Where are you reading that there is?
There is one discrepancy in the datasheet, in that it mentions "50 MHz" for SPI2 at the start of the SPI chapter, but only "40 MHz" in the AC timing specs at the end, for "SPIx dedicated pins".
That does not mean that every SPI port has dedicated pins.
Worst forum problems are now fixed, but the damn firewall is still there.
