-- # ********************************************************************************************* #
-- # This unit provides 8 maskable external interrupt lines with according ACK lines. The IRQ #
-- # can be globally set to trigger either on a high-level or on a rising edge. Each line has a #
-- # unique enable bit. The acknowledge output is set high for one clock cycle to confirm the #
-- # interrupt has been sampled and has also been cpatured by the handler function. #
-- # All external interrupt requests are forwarded to a single CPU interrupt. The according #
-- # trigger on a high level (use external edge detectors if required). Each line has a unique #
-- # enable bit. The acknowledge output is set high for one clock cycle to confirm the #
-- # interrupt has been sampled and has also been cpatured by the according handler function. #
-- # All external interrupt requests are forwarded to a *single CPU interrupt*. The according IRQ #
-- # has to check the SRC bits in the unit's control register to determine the actual source and #
-- # start the according handler function. #
-- # If several IRQs occur at the same time, the one with highest priority is executed while the #
-- # others are kept in a buffer. The buffer is reset when the global enable flag of the unit is #
-- # cleared. #
-- # ext_irq_i(0) has highest priority while ext_irq_i(7) has the lowest priority. #
-- # cleared. ext_irq_i(0) has highest priority while ext_irq_i(7) has the lowest priority. #
-- # Each enabled interrupt channel can also be triggered by software using the sw_irq_x bits. #
