The LCD displays a decimal dot in the left-most digit to indicate that it is in Brownout mode, as shown below:

.

H

E

L

L

O

The following commands can be entered via the CLI in Brownout mode:

•

BL – enters LCD mode

•

BS – enters Sleep mode.

•

BWSn – enters sleep mode for n seconds, then returns to Brownout mode

•

BWMm – enters sleep mode for m minutes, then returns to Brownout mode

In Sleep Mode, almost all functions are disabled. Only the RTC and the wakeup timer are still active. The
wakeup signal from the timer and the pushbutton (SW2 on the Demo Board) take the 71M6521 back to
Brownout mode.

A hardware reset, while in any battery mode, takes the 71M6521 back to Brownout mode.

Precautions when adding a battery:

When a battery or other DC supply is added to a Demo

Board that is powered down, the 71M6521 Demo Code will cause the chip to enter Brownout
mode and stay in Brownout mode. It is possible that the VBAT pins of the chip draws up to 1mA
in this state, since the I/O pins are not initialized when Brownout mode is entered from a state

where the chip is powered down (if Brownout mode is entered from Mission mode, the I/O pins are properly
initialized, and the chip will enter Sleep mode automatically causing much lower supply current into the
VBAT).

To prevent the battery from being drained at an excessive rate, the RESET button should
be pressed right after inserting the battery. For this to work, the RESET button must be
enabled by removing R91.

In general, the firmware for the 71M6521 has to be written to handle the case of
connecting a battery to a powered-down board (since in a factory setting, batteries will
most likely be added to meter boards that are powered down). The firmware must
immediately enter sleep mode in this situation.
