HL13 LED is designed to determine the current active configuration EEPROM (Fig. 2.4, Table 2.1,
subparagraph 4.2.5
Booting the Program Configuration Unit’s FPGA (main/reserved)).

Reserved
The main and reserved configuration EEPROMs can be modified both locally from NAND flash
drive, and remotely via the Gigabit Ethernet interface (the MCU operates at the rate of up to 100
Mb).

Real Time Clock
In order to record events, as well as to provide the autoconfiguration functions, the
KIC551/KIC551RC module features a real-time clock implemented by the MCU hardware.
A 3.0 V lithium battery is used to supply power to the real-time clock in a de-energized state (Fig.
2.4). Please use RENATA CR1632 battery or other compatible models. The module can work
without a battery. If no battery is used, setting the real time clock will be required every time the
power is turned on, otherwise the clock data might be invalid.
