different module combinations.
A 0.1-Farad capacitor is provided on the eZ80L92 Module as a short-term
battery backup for the RTC (see the
part number of the capacitor made by Panasonic is EECS0HDV. The
capacitor is connected to RTC_VDD to provide power to the RTC when
main power to the chip is removed; it is also connected to the 3.3V supply
to the chip for recharging. The RTC can operate down to 3.0V; it requires
10µA of current. The (keep alive) time this capacitor can supply power to
the RTC, from 3.3V to 3.0V, is approximately 3000 seconds, or 50 min-
utes.

Flash Loader Utility

The Flash Loader utility resides in the boot sector of Flash memory,
located on the eZ80L92 Module. The Flash Loader utility allows the
operation of the Boot Block utility or jumping to user application code.
Please refer to the
