Is it possible to fire an interrupt when data is received via the software UART on a 12F675? It doesn't have support for INT_RDA.
If not possible, can someone provide an example of a work-around?
Thanks!

Map your receive pin on the GP2/INT pin and configure the GP2/INT external interrupt to detect falling edges (clear the INTEDG bit INTCON). This way you'll get an interrupt on the start bit of your RS232 data.
