Nano ESP32

Is your feature request related to a problem?

Using the attached example Ticker_Test.zip I measured the minimum period of Ticker.attach(). For Arduino Nano ESP32 the minimum period is 1ms. Any value <1E-3 results in a 50us period.

However, for ESP32-WROOM-32UE the minimum period is 50us. Any value <5E-5 results in a 50us period.

I have a LIN library which works well with Espressif and a ~300µs Ticker period. However Nano ESP32 fails, because 1ms is too long and 50µs is too short.

Describe the solution you'd like

Is it possible to reduce the minimum period similar like Espressif? For your help thanks a lot in advance!
