Set the bit resolution of the PWM (analogWrite) for SAMD21 and SAMD51 boards. i.e. analogWriteResolution(). Usually 8..16 bits.

counts the time when the EN input is true saves the counted time to eeprom if power off

Read and write unsigned integer value 16bit (0-65535) from /to the internal eeprom

Encoder with button and set limits. When the extreme value is reached, the next transaction continues counting from the extreme opposite value. For example, with limits from 1 to 4, when the value of 4 is reached, continues counting from 1 and vice versa.
