Warning!
To prevent shorting, premature failure or damage to the lithium battery, do not
place the board on a conductive surface such as metal, black conductive foam or
the outside surface of a metalized ESD protective pouch. The lithium battery may
explode if mistreated. Do not recharge, disassemble or dispose of in fire. Dispose
of used batteries promptly.
Normal battery voltage should be at least 3.0V. If the voltage drops below 3.0V, contact the
factory for a replacement (part number HB3/0-1). The life expectancy under normal use is
approximately 10 years.

NTERRUPT
The EBX-22 can be configured to generate an interrupt if the 5V power rail exceeds 5.25V or
drops below 4.75V. These voltage thresholds conform to the power supply recommendation of
5V +/- 5%. The voltage alert interrupt is enabled in CMOS Setup on the Board tab. Interrupts
available for this purpose are IRQ 3, 4, 5, and 10. (The NMI, non-maskable interrupt, setting is
reserved for future use).
Note:
The IRQ for voltage and temperature monitoring is shared. When the Voltage or
Temperature IRQ option is set, the selected IRQ will apply to both voltage and
temperature monitoring if they are enabled.
