3. Since setting up the HESC is only done infrequently, only two commands are provided. Function ActiveEEcmd()
sets the location for the next EEprom read or write, and if the location should auto increment. Function EEPromCmd()
reads or writes the EEprom location as set by ActiveEEcmd().

() capacity value is expressed in either current (mAh at a C/5 discharge rate) or power (10mWh at a
P/5 discharge rate) depending on the setting of the capacity mode bit.
*** High byte = major version, Low byte = minor version
**** Low byte = location 0 to 127, High byte: no auto increment = 0; auto increment = 1
