7.3 WAKE-UP SYSTEM MANAGEMENT
In order to reduce module power consumption, a wake-up period parameter setting system is incorporated.
This system enables modification of the module wake-up period (default setting 1 s) by entering a time and
day of the week :
 The wake-up period default value may be modified;
 Two time-windows with different wake-up periods may be defined;
 Each day of the week may be set in one of the following three cases :
• Wake-up period default setting
•
Wake-up according to predefined time windows
• No wake-up period (for safety reasons, the module is not disabled on reception and it
wakes up every 10 seconds)

0x09 Enable wake-up periods by day of week 1 R/W 0x00
7.3.2 Choice of wake-up mode
These modes are directly dependant on the 'wake-up system status word' configuration and the values of
parameters associated with each mode.

Case n°2 : Periodic wake-up in specific time windows for certain days of the week, periodic wake-up
for the other days
0x02 Case n°3 : Periodic wake-up for certain days of the week, periodic wake-up disabled for the other days

Case n°4 : Periodic wake-up in specific time windows for certain days of the week, periodic wake-up

Remark: before enabling a specific wake-up mode, the parameters associated with this mode must
first be set.
