AMD-K6™-IIIE+ Embedded Processor Data Sheet
Table 70. TCK Waveform and TRST# Timing at 25 MHz
Notes:
1. Rise/Fall times can be increased by 1.0 ns for each 10 MHz that TCK is run below its maximum frequency of 25 MHz.
2. Rise/Fall times are measured between 0.8 V and 2.0 V.
3. Asynchronous.
Table 71. Test Signal Timing at 25 MHz
Notes:
1. Parameter is measured from the TCK rising edge.
2. Parameter is measured from the TCK falling edge.
