Table MCU System Test MCU System Test Step Procedure Expected Results Observations 5. Measure the current draw Current draw measures around 235 micro amps. 6. Press button 1 of the MCU The MCU come out of low power mode 1. LED1 flashes and the MCU enters low power mode 2. 7. Measure the current draw. Current reading measures at around 0.9 micro amps. 8. Press button 1 of the The MCU enters active MCU. mode and flashes LED1 9. Measure and write down Voltage measurement is the voltage at BattMon pin. around half the battery Testing MCU battery voltage. monitoring. 10. Press Button1 of the MCU. The number of times the Count the number of times LED flashes represents the LED flashes. the ones place of the voltage measured in step 9. If the voltage measure at the BattMon pin was 2.35, the LED flashes two times. 11. Press Button1 of the MCU. The number of times the Count the number of times LED flashes represents the LED flashes. the tenths place of the voltage measured in step 9. If the voltage measure at the BattMon pin was 2.35, the LED flashes three times.
