The active display shows the following as displayed in
• clock time
• time standard
• alarm indicator
• brightness percentage (PWM)
• temperature value
• temperature standard
• system clock frequency
To escape Active mode the user has the option to press RB1 (Select) at any time. The
user also has the option to escape Active mode if the alarm is enabled and the specified
time is met. Upon exiting, the user will return to the “8-Bit XLP Main Menu”.

In Conserve mode the CPU is off and peripherals are on. In this power-saving state,
the peripherals are still active. Through this method we are able to continue monitoring
the Timer1 (32 kHz) signal, which allows the clock to stay accurate. To showcase this
feature upon entering the mode, the device will remain asleep until a set value of time
has elapsed. The wait period before waking from Sleep determined by the user is found
under [SettingsTimeWake Up].
The user can choose to wake-up every 15, 30 or 60 seconds or to not awake at all. By
software default this value is 15 seconds. When the device “wakes up” from Sleep, it
will run in Active mode until a set value of time has elapsed. The display period is deter-
mined by the user, found under [SettingsTimeDisplay Length]. The user can
choose to have a display length of 5 or 10 seconds. If “wake up” is None, the display
length will be set to 0. By software default the display length is 5 seconds.
To escape Conserve mode, the user has the option to press RB1 (Select) at any time.
This feature shows a wake-up based upon an interrupt (INT1). The user also has the
option to escape Conserve mode if the alarm is enabled and the specified time is met.
Upon exiting, the user will return to the “8-Bit XLP Main Menu”.
