The EVM supports a manual switch [SW2] for power control to the EVM. The switch [SW2] is a two-position switch. The OFF position disconnects input power from on-board circuitry. The ON position connects the input power.
Three status LEDs [LD5][LD6][LD7] are used to communicate power status to the user.
LED | ‘ON’ State | ‘OFF’ State |
---|---|---|
[LD7] | Power switch [SW2] is in the ON position, and input power is being supplied to the EVM. | Power switch [SW2] is in the OFF or there is some other issue causing power to not be supplied. |
[LD6] | MCU domain of the EVM is powered | MCU domain of the EVM is not powered/OFF 1 |
[LD5] | MAIN domain of the EVM is powered | MAIN domain of the EVM is not powered/OFF 1 |
