d. When the module enters a Sleep 1 state, the backup RAM is turned on while the main RAM
power is turned off. Thus, when the module wakes up, hot start can run as soon as the firmware
is downloaded from the flash to the RAM. This happens because data is retained in the backup
RAM. There are three ways to wake up the module from a Sleep 1 state: module timeout, using
the wakeup pin, interrupting via interface. Any data on the UART/I2C can wake the module from
the Sleep 1 state. It is recommended to send a dummy data before sending an actual command
to prevent losing transmission data when the module wakes up.
Note: Sleep 1 has a lower consumption than Sleep 0 but the TTFF time for Sleep 1 is slower.
