The ETC register is a shadowed EEPROM register that contains the accumulated time in 250ms increments that the EVENT pin
has been held high. On power-up, on every rising edge of the EVENT pin, and after an I2C write to the ETC register, the value
from the shadowed EEPROM location is loaded into the ETC counter memory (SRAM). When the EVENT pin is high, it is this
SRAM memory that is incremented once every 250ms. On the falling edge of the EVENT pin, this value in SRAM memory is then
written to the shadowed EEPROM memory to store the accumulated time in 250ms increments.

The Event Counter Alarm Limit is a shadowed EEPROM register, and when the Event Counter register value equals or exceeds
the Event Counter Alarm Limit value, the EVENT flag bit (EVENT AF bit, Register 01h, bit 1) goes active high. When the Event
Counter register value drops below the Event Counter Alarm Limit value, the EVENT AF bit automatically clears.
