7.3 DC ELECTRICAL CHARACTERISTICS
(T

= -40°C to +125°C and V
DD
= 5V unless otherwise specified)
Notes:
1. Hysteresis voltage between switching levels. Based on characterisation results, not tested.
2. CPU running with memory access, no DC load or activity on I/O’s; clock input (OSCIN) driven by external square wave.
3. No DC load or activity on I/O’s; clock input (OSCIN) driven by external square wave.
4. Except OSCIN and OSCOUT
5. WAIT Mode with SLOW Mode selected. Based on characterisation results, not tested.
