This figure provides the AC test load for the local bus.
Figure 36. Local Bus AC Test Load
Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tLBIXKH1 symbolizes local bus timing (LB)
for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for clock one (1).
2. All timings are in reference to falling edge of LCLK0 (for all outputs and for LGTA and LUPWAIT inputs) or rising edge of LCLK0
(for all other inputs).
3. All signals are measured from NVDD/2 of the rising/falling edge of LCLK0 to 0.4 NVDD of the signal in question for 3.3-V
signaling levels.
4. Input timings are measured at the pin.
5. tLBOTOT1 and tLALETOT1 should be used when RCWH[LALE] is not set and the load on LALE output pin is at least 10 pF less than
the load on LAD output pins.
6. tLBOTOT2 and tLALETOT2 should be used when RCWH[LALE] is set and the load on LALE output pin is at least 10 pF less than
the load on LAD output pins.
7. tLBOTOT3 and tLALETOT3 should be used when RCWH[LALE] is set and the load on LALE output pin equals to the load on LAD
output pins.
8. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered through
the component pin is less than or equal to the leakage current specification.
