Multiple ISRs (interrupt service routines)

I'm using the Keil MCB900 eval board with a P89LPC938 at 7.3728MHz and the LPC900 development tools (demo version). I'm using most of Mark Odell's UART and Timer code. I have setup Timer 1 as the...

Interrupt Service Routine (ISR) and os_mut_wait()

When ISR calls os_mut_wait() the processor generates an exception. Is os_mut_wait() prohibited from being called from an ISR?

Does EPM900 support single step running in (ISR)interrupt service routine ?

I linked the EPM900 to PC's RS232 port to emulate serial communication. In main function an infinite loop is written to wait for serial port IRQ. A break point is set in the start of ISR. When EPM900...
