M-78F0714 Micro-Board for µPD78F0714 Microcontroller
3.4 Measuring Power Consumption of the µPD78F0714
The power select jumper, 2JP1, is designed to connect an ampere meter to measure accurate power
consumption for the µPD78F0714, regardless of which power source is selected. To measure power
consumption for the µPD78F0714:
1. Remove the power select jumper on 2JP1.
2. Connect an ampere meter on the 2JP1 terminals.
