The MCU normally stays in Stop mode to conserve power. Each time it wakes up, a status
message is sent to indicate the reason for the wake up. Table 7 lists these status message
descriptions.
Note:
In Table 7,
‘*’ indicates MCU wake up and ‘.’ indicates MCU returning to Stop mode. When
Motion Detected status is sent, an ASCII BELL character (0x07) is also sent. Some terminal
applications can interpret this and provide an audible indication of motion detection
