TEST CONDITIONS
The ac signal specifications (timing parameters) appear in
Table 29 on Page 27. These include output disable time, output
enable time, and capacitive loading. The timing specifications
for the processor apply for the voltage reference levels in
Output Disable Time
Output pins are considered to be disabled when they stop driv-
ing, go into a high impedance state, and start to decay from their
output high or low voltage. The time for the voltage on the bus
to decay by ΔV is dependent on the capacitive load, CL and the
load current, IL. This decay time can be approximated by the
following equation:
The output disable time tDIS is the difference between
tMEASURED_DIS is the interval from when the reference signal
switches to when the output voltage decays ΔV from the mea-
sured output high or output low voltage. tDECAY is calculated
with test loads CL and IL, and with ΔV equal to 0.4 V.
