+ * charging/discharging is disabled. Therefore, in addition to the mask for

+ * gauge, the charge/discharge FET status is found in Operation Status (0x54),
+ * but a read of Manufacturer Access (0x00) will return the lower 16 bits of
+ * Operation status which contains the FET status bits.
+ *
+ * The assumption for battery types supported is that the charge/discharge FET
