What is the best way to monitor mode change in Power manager demo

[sukhwan]

I'm trying to monitor mode changes in Power mode demo application on evkmimxrt595 board such as frequency change using an oscilloscope. Could you recommend ways to monitor the change of the modes?

Power Manager Demo.

The "user key" is: SW2

Select an option

1. Sleep mode

2. Deep Sleep mode

3. Deep power down mode

4. Full deep power down mode

I haven't find any information on links that you shared, how and where to monitor the change of the mode such as by measuring clock frequency change on a pin or voltage change specifically. How can I confirm power consumption would be reduced in each mode?

Hi,

• Please look up the datasheet to find the details in each working mode, e.g Table 10~15 show different Power consumption in different mode https://www.nxp.com.cn/docs/en/data-sheet/IMXRT500EC.pdf 
• MIMXRT595-EVK Board User Manual[UM12285] also provides how to measure board power in section 6.

Hi,

Please see below link to find i.MX RT500 power managment, it offers a rich set of peripherals and very low power consumption, this note describes how to use the power management in i.MX RT500, but this document does not replace the datasheet or the reference manual.

Besides, here is a full example to show how to switch different power mode of RT595.
