AC inputs during testing are driven at V
Timing measurement are made at V
For timing purposes as port pin is no longer floating when a 100 mV change from load
voltage occurs and begins to float when a 100 mV change from the loaded V
occurs. I
Valid in normal clock mode. In X2 mode XTAL2 must be changed to XTAL2/2.
