Describe the enhancement

The ability to read/write the user's 56 bytes of SRAM on the DS1307 chip allows it to be used to store the current value of the counter registers (the Pulse Counter component) and restore them when the microcontroller (ESP32 and others) is rebooted. This eliminates the wear and tear of the microcontroller's flash memory.

Use cases

Storage of user variables, pulse counter, and accumulation of temperature and light level readings

Anything else?
