7.3 Reset Status
The reset status of a module is set when the module is powered-on, or when
the module is reset by the Module Watchdog, and is cleared after responding to
the first $AA5 command. This can be used to check whether the module has
been previously reset. When the response to the $AA5 command indicates that
the reset status has been cleared, it means that the module has not been reset
since the last $AA5 command was sent. When the response to the $AA5
command indicates that the reset status has been set and it is not the first time
the $AA5 command has been sent, it means that the module has been reset and
the digital output value has been changed to the power-on value.
