4.2.1 Idle Mode
After the host MCU application calls the ATWINC15x0 driver initialization
m2m_wifi_init
API, the ATWINC15x0 remains in Idle mode waiting for any command to
change the mode or to update the configuration parameters. In this mode, the
ATWINC15x0 enters into Power Save mode
which disables the IEEE 802.11 radio and all unneeded peripherals and
suspends the ATWINC15x0 CPU. If the ATWINC15x0 receives any configuration
commands from the host MCU, it updates the configuration, sends back the
response to the host MCU, and then returns to the Power Save mode.
