I would like to use the Teensy 4.0 as a simple signal generator to produce digital signals. The intent is to use three I/O pins and configure them as outputs. The 1st signal has a frequency of around 30 HZ, the 2nd signal has a frequency of around 8 KHz, and the 3rd signal has a frequency of around 10 MHz.

The code for generating the signals does not involve any math or computation. So, the code will be just a few lines long with no math or computation in between.
Can I achieve producing a 10 MHz signal?

Thanks,
Mo
