Additional feature: energy harvesting commands

M24LRXXE devices, such as the M24LR16E-R, have the Energy Harvesting capability.

Clicking the Display Energy Harvesting commands button (see Figure 64) opens a new

window which allows to manage Energy Harvesting (see Figure 65). Several RF commands

are available:

●

Click the Read config byte button to send a ReadCfg command to the M24LRXXE

and display the value of the config byte.

●

Click the Write E.H. config button to send a WriteEHCfg command to the M24LRXXE

in order to change EH configuration (EH_MODE and EH config bits).

●

Click the Write D.O. config button to send a WriteDOCfg command to the M24LRXXE

and change Digital Output config.

●

Click the Check E.H. enable button to send a CheckEHEn command to the

M24LRXXE and display the value of this Control Register.

●

Click the Reset/Set EH buttons to send a SetRstEHEn command to the M24LRXXE

and deactivate/activate energy harvesting (when possible)

Refer to the datasheets for full details on energy harvesting commands.
