Optimize the scanning interval of schedule scan

The peak of current is 80mA for schedule scan. In the past, the
interval of schedule scan is 20s, it would increase the average
current by 20mA.

This change is to optimize the scanning interval so that the
average current can be reduced to less than 1mA
Min_Period: 48s
Max_Period: 500s
Exponent: 10
Step count: 7

48s, 48s, 48s, 48s, 48s, 48s, 48s, 480s,..., 480s, ...
