Interrupt Registers
The CIMaX handles five interrupt sources issued from modules detection, modules IRQ and
external device. Each interrupt is latched in the Interrupt Status Register. Each bit in this register
can generate an interrupt to the microprocessor when set and when the corresponding mask bit
in the interrupt mask register is set.
In addition, the interrupt output pin structure and level can be configured to match the host hard-
ware requirements.
