A bar over a signal name indicates that the signal is active low, such as
IRQ_OUT (interrupt out). Active-low signals are referred to as asserted
(active) when they are low and negated when they are high. Signals that are
not active low, such as IRQ (interrupt input), are referred to as asserted when
they are high and negated when they are low.
Internal signals are shown throughout this document as lower case and in
italics. For example, sys_logic_clk is an internal signal. These are discussed
only as necessary for understanding the external functionality of the device.
