Figure 7-20 shows the output enable and disable times due to a HIGHZ TAP instruction.
Figure 7-21 shows the output enable and disable times due to data scanning.The timing
parameters used in Figure 7-20 and Figure 7-21 are listed in Table 7-20.
Figure 7-20 shows the T
when the HIGHZ TAP instruction is loaded into the instruction register.
Figure 7-21 shows the T
when data scanning, due to different logic levels being scanned through the scan cells
for ABE and DBE.
