    Hi guys,

    I'm using an NEC v25 upd70320 MCU ( and an itl710 touchscreen (

    Right now I have the two connected via serial port and I poll to see if there is anything new on the serial port. What I would like is everytime I press a button on the touchscreen, it should generate an interrupt on the MCU. I'm not really sure how to set this up, I know a bit about interrupt programming but not how to set up the hardware. Any help would be great.
