RECOMMENDED OPERATING CONDITIONS (Cont’d)

(TA=0 to +70

oC, V

DD-VSS=6V unless otherwise specified)

Notes:

1. CPU running with memory access, all I/O pins in input mode with a static value at VDD or VSS; clock input (OSC1)

driven by external square wave, LVD enabled.

2. All I/O pins in input mode with a static value at VDD or VSS; clock input (OSC1) driven by external square wave, LVD

enabled.

3. WAIT Mode with SLOW Mode selected, LVD enabled. Based on characterisation results, not tested.

4. All I/O pins in input mode with a static value at VDD or VSS, I/O PORT CHARACTERISTICS

T = 0... +70

oC, voltages are referred to V

SS unless otherwise specified:

* Note: Hysteresis voltage between Schmitt trigger switching levels. Based on characterisation results, not tested.
