I have to interface ADS1224 with RM48l90pge
I think to do this with spi2 pins which are sclk and somi pins for communication and cs0 and cs1 for mux controlling (behaves as IO pins)
to recive th data I use 3 data formats
FMT0 as a 16 bits width recived data
FMT1 as 9 bits data for complete cycle
and FMT2 of 2 bits for enable the callibration cycle
I have two problems
1.how can I use the ISR
the ISR is configured for RXINT for ISR enable and spigetdata function for reading data in ISR mode
but when I use the function there is no RXINT ISR
2.There is a way to recive an ISR on somi pin when the falling edge from the ADS happened which tell me that there is new data ?
Or I have to use on of GIOA pins to recive the ISR ?
