Erik,

Yes, it's user defined (within limits).  Write to the Bus Interface Unit's
MCR to set the "base" interrupt vector for the CTM4.  PWM5 would use vector
base+5.  You've probably already figured out that it can be at the IPL of
your choice using the PWMSIC register.

See Table 10-7 in the MC68376UM for the breakdown.

Subject:    [68300] pwm interrupt for 68376


I am having trouble setting up the interrupt that will fire after
completion of each pwm period.  I previously posted but made a
mistake when I said that I was using the TPU to handle the PWM
signal.  I am actually using the PWM submodule that is part of the
CTM4.

My question is: What is the interrupt vector that is selected if the
PWM5SIC register is set to trigure an interrupt?  Is is user defined?

Thanks,
Erik
