MOTOROLA
Num
1. All timings are calculated for normal port drives.
2. Crystal input is required to be within 45% to 55% duty.
3. Reduced drive must be off to meet these timings.
4. Unequalled loading of pins will affect relative timing numbers.
5. This characteristic is affected by clock stretch.
6. Without TAG enabled.
