1. Clock rise and fall times are not tested.
2. A float condition occurs when the maximum output current becomes less than I_LO. Float delay is not tested; however, it should not be longer than
the valid delay.
3. LAD31:0, BADAC, HOLD, LOCK and READY are synchronous inputs. IAC/INT₀, INT₁, INT₂/INT_R and INT₃ may be synchronous or asynchronous.
