PIC32 100 pin SPI ports

Just to make it a bit easier - here is a list of SPI pins on the 100 pin PIC32 chips.

The PIC32MX795 has four SPI ports, named SPI1, SPI1A, SPI2A and SPI3A. They are all equal.

SPI1:
namepinport
SCK70RD10
SDI9RC4
SDO72RD0
not SS69 RD9


SPI1A:
namepinport
SCK48RD15
SDI52RF2
SDO53RF8
not SS47RD14


SPI2A:
namepinport
SCK10RG6
SDI11RG7
SDO12RG8
not SS14RG9


SPI3A:
namepinport
SCK39RF13
SDI49RF4
SDO50RF5
not SS40RF12


On the EasyPIC Fusion v7 from Mikroelektronika, the only SPI that has all the necessary pins on the same 10 pin connector is SPI3A


For reference, a 40 pin PIC18F has the following SPI
namepinport
SCK18RC3
SDI23RC4
SDO24RC5
not SS7RA5
