IATA charge control is a useful feature in production to enable the device to charge until True RSOC is below IATA RSOC Threshold, and then to restrict charging by disabling the CHG FET. The host sends the MAC command IATA_Charge() (0x00F3) to start the charging event and the restriction only holds for the charging event immediately after the command is sent. The CHG FET is enabled and charging is allowed again when the device detects discharge current greater than Dsg Current Threshold. OperationStatus[IATA_CTERM] is set when IATA charge control is active.
