Module Power Supply Voltage Drop Detection

This function detects a voltage drop of the module power supply.

This function makes troubleshooting easy when the voltage of power supplied to the FPGA module drops or when poor

connection in the wiring occurs. Note that the voltage to be monitored for a module power supply voltage drop is 20.4V.

If a drop in the voltage of the module power supply is detected, the module enters the following state and an error is notified.

• The module power supply voltage drop error (error code: 1080H or 1081H) is stored in Latest error code (RWr0).

• Error flag (RXA) turns on.

• When an error is detected, since the power supply environment is out of specification range, the operation

is not guaranteed.

• A power supply voltage drop is not detected in the event of a sudden power failure or when power-off

operation is performed.

• The voltage to be monitored varies depending on the environment.
