2.3.2 Power Control

The EVM supports a manual switch [SW1] for power control to the EVM. The switch [SW1] 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 [LD7][LD8][LD9] are used to communicated power status to the user.

[LD7]Power switch [SW1] is in the ON position, and input power is being supplied to the EVM.Power switch [SW1] is in the OFF or there is some other issue causing power to not be supplied.
[LD8]MCU domain of the EVM is poweredMCU domain of the EVM is not powered/OFF (1)
[LD9]MAIN domain of the EVM is poweredMAIN domain of the EVM is not powered/OFF (1)
Note: The power management IC (PMIC) includes functions to monitor power domains, including over/under voltage, over current, and residual voltage. If the PMIC detects and error, then the PMIC can transition to safe-mode where the PMIC powers down both the MCU and MAIN domains.
