Battery Backup Mode
The battery backup mode is activated when the power for the GPS receiver is turned off and power-on reset
goes to low level. The timer clock continues to operate even when power-on reset goes low, but all other clock
are fixed high and the LSI is set to the low power consumption mode. At this time, the RAM data is held and
the registers are initialized.
Battery backup mode is canceled by setting power-on reset to high.
