A non-volatile integer counter with a calculation result from 0.00 to 4294967000.00. The result of the calculations is converted into a 32-bit unsigned integer, represented as four bytes. The result of the calculations is recorded in the eeprom by a signal from the voltage monitoring port. After resuming the voltage on the chip, the eeprom is read first, followed by further calculations. The resulting number can be further used in subsequent calculations or displayed on the LCD.

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
