n Bit 5 ... 0: Interrupt behavior:
–
Bit 0: Process interrupt HW gate open
Bit 1: Process interrupt HW gate closed
Bit 2: Process interrupt overflow
Bit 3: Process interrupt underrun
Bit 4: Process interrupt comparison value
Bit 5: Process interrupt end value
By setting the bits you may activate the wanted process inter-
rupts.
n Bit 7 ... 6: reserved
*) This is not supported at this time.

n Diagnostic interrupt
–
0000h = de-activated
– 0001h = activated

n reserved
n Here you activate respectively de-activate the diagnostic function.
n A diagnostic interrupt occurs when during a process interrupt exe-
cution another process interrupt is initialized for the same event.
