You have to write to USIU.SIMASK.R to enable the interrupt level you set PIT to when you wrote to USIU.PISCR.R. I'm almost certain there is an app note on PIT and DEC on the Freescale site. Regarding the function you previously posted for confirmation - if you are not generating a PIT interrupt and therefor not executing this routine, it can't be your source of error. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of sripathy23 Sent: Wednesday, September 07, 2005 3:20 PM To: [email protected] Subject: [MPC500] PIT interrupt Dear allan Have you set MSR[EE] to allow interrupts?
