Why is this AVR-only code in the Teensy documentation?

[raffahacks]

I found this page on Teensy docs: https://www.pjrc.com/teensy/prescaler.html
After some syntax errors and googling, I found out that the code can be used only on AVRs. Why is this page without any notice in the Teensy Docs?

teensy 2 is avr.

Then at least I'd add a notice saying "this code is for teensy 2 and other AVR-based boards". I got quite upset, as it was necessary for my Teensy 3.1 project and I bought it also because of this function

I've updated that page with a message that it only applies to the older Teensy 2.0 boards.

I got an answer from Paul! That's incredible

Thanks for the fast solution. Btw, do you know if it's possible to do something similar to temporarily reduce clock speed?

I looked at this library before, but does it support wake up using a button?

If you look at the examples, there are examples to wake the Teensy from sleep using any digital button that can generate interrupts, and from deepsleep using the buttons that can be configured for touch sensing.

On the Teensy 3.1, all digital input pins can be configured for interrupts. On the Teensy LC, pins 2-15 and 20-23 can be configured for interrupts.

On the Teensy 3.1, pins 0-1, 16-19, 22-23, 25, and 32-33 can be configured for touch sensing. On the Teensy LC, 0-1, 3-4, 16-19, and 22-23 can be configured for touch sensing.

Yes i does take a look at example: pushbutton_pullup_deepSleep, digital wakeup triggers work for all sleep modes in the library.
