Quick Start Guide for AS064 Air Freshener
This application note describes the working of an Automatic Air Freshener, using a 10-pin RL78/G15
microcontroller and a "Single Pole Four Throw" slide switch timed at 40 minutes, 20 minutes and 10 minutes. 12
bit interval timer is used for this application. This wakes up the microcontroller from stop mode every 273 milli
seconds, to perform several operations based on the state of microcontroller.
