The tables in this section list the following AC characteris-
tics:
• Output delays
• Input setup requirements
• Input hold requirements
• Output float delays
• Power-up sequencing requirements
The default levels for measurement of the rising clock edge
reference voltage (V
Table 8-10. Input or output signals must cross these levels
during testing. Unless otherwise specified, all measure-
ment points in this section conform to these default levels.
