I am going to be using a serial device that will generate a pulse on the MISO line whenever one of its 16bit registers has been addressed and is ready to receive the next byte.
I'm not sure than the PIC will perform a BTFSS or BTFSC properly if the SPI is enabled, even if the TRIS is set as an input for that pin. I really don't want to have to disable the SPI in the middle of the process because I'm concerned about issues that might create (may be a non issue - I don't know).
Does anyone know if the PIC (A 16F818) will allow me to poll the SDI pin with the SPI enabled?
Thanks.
