indicate the states of output voltages of the relevant module’s power supply
sources.
Controlling the current status of EEPROM configuration
This function is designed for proper addressing to configuration EEPROM while operating in
the automatic mode at high speed, mainly in case of autonomous operation of microcontroller unit
with EEPROM (Table 4.15).

Control of the installed host and peripheral modules by slots
The specified function returns data on the state of peripheral slots of the system. All the devices
will be recognized: both standard ones with the lines PCIE_PRSNT# set to logical zero and the
special-purpose ones specified in the system Program Configuration Unit (in this case the lines
PCIE_PRSNT# of these modules can be used as outputs of Reset signal to be broadcasted by
KIC551/KIC551RC to the other peripheral devices in the backplane).

The slots are numbered in accordance with the numbers specified on the backplane (Slot #1
–
system slot).
The modules installed into peripheral slots and not defined in the register 04
“System Status”,
are not detected by the system and will be operating on an individual basis (
there won’t be any in
the general PCI space). In this case, communication with these modules can be set via Gigabit
Ethernet interface of the backplane and via I

C bus.
