Asserted
Active-high (positive true) signals are asserted when in
the high electrical state (near power potential). Active-
low (negative true) signals are asserted when in the low
electrical state (near ground potential).

Deasserted
A signal is deasserted when in the inactive state. Active-
low signal names have “_L” appended to the end of the
signal mnemonic. Active-high signal names have no “_L”
suffix. To reduce confusion when referring to active-high
and active-low signals, the terms one/zero, high/low, and
true/false are not used when describing signal states.
