(Note)
Initialization from Host :
- The IC will initialize reading the battery temperature until Initialization sequence with serial port is executed. (Please see EVB manual for sequences.)
Control from Host :
- The Remaining State of Charge (RSOC) is normally read periodically.
- To read temperature the part will need a sequence of instructions and then returned to RSOC reading.
