SUPPLY CURRENT CHARACTERISTICS (Cont’d)
12.4.3 RUN and SLOW Modes (ROM devices)
12.4.4 WAIT and SLOW WAIT Modes (ROM devices)
Notes:
1. Data based on characterization results, tested in production at V
2. Measurements are done in the following conditions:
- Progam executed from RAM, CPU running with RAM access. There is no increase in consumption for if programs are
- All I/O pins in input mode with a static value at V
- All peripherals in reset state.
- CSS and LVD disabled.
- Clock input (OSC1) driven by external square wave.
- In SLOW and SLOW WAIT mode, f
