How to get into the deep sleep for teensy 4.1

[WaveSimm]

Thanks for your advice in advance.
I am a hardware guy so, don't have enough knowledge..
Is it possible to get into deep sleep mode for teensy 4.1 using Micropython?

Thanks again.

machine.deepsleep([time_ms]) is support for the MIMXRT port including Teensy 4.1 .

I can't get this method. I am using 1.91

machine.deepsleep(10000)
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'module' object has no attribute 'deepsleep'

There is machine.deepsleep() in the current version of MicroPython.

yes!!!!! It works well with the new version. I was using 1.91 before.
You save my project!!!
