8.4 GENERAL TIMING CHARACTERISTICS
Notes:
1) Unless otherwise specified, typical data are based on T
lines and are not tested.
2) CPU running with memory access, all I/O pins in input mode with a static value at V
off; clock input (OSC1) driven by external square wave.
3) All I/O pins in input mode with a static value at V
external square wave.
4) All I/O pins in input mode with a static value at V
5) Data based on characterization results, not tested in production.
