9.5.3 UNSEALED to FULL ACCESS
UNSEALED to FULL ACCESS instructs the device to allow full access to all standard and extended registers and data flash. The device is shipped from TI in this mode. The keys for UNSEALED to FULL ACCESS can be read and changed via the MAC command SecurityKey() when in FULL ACCESS mode. Changing from UNSEALED to FULL ACCESS is performed by using the AltManufacturerAccess() command, by writing the first word of the Full Access Key to AltManufacturerAccess(), followed by the second word of the Full Access Key to AltManufacturerAccess(). In FULL ACCESS mode, the command to go to boot ROM can be sent.

Request current security mode of the device.
12.2.30 AltManufacturerAccess() 0x0054 OperationStatus() SEC1, SEC0 (Bits 14, 13): SECURITY Mode 0, 0 = Reserved 0, 1 = Full Access 1, 0 = Unsealed 1, 1 = Sealed
12.1.1 0x00/01 ManufacturerAccessControl() SEC1, SEC0 (Bits 14, 13): SECURITY Mode 0, 0 = Reserved 0, 1 = Full Access - doesn't work correct! It's (0, 0) in fact 1, 0 = Unsealed 1, 1 = Sealed
| void setEnabledChargingSocThreshold | ( | bool | enabled | ) |
Enable or Disable turning charging FET off at 60% SOC.
| void setOccThreshold | ( | int | occThreshold | ) |
Overcurrent in Charge trip threshold.
13.10.3 OCC - Overcurrent In Charge: Protections; OCC; 0x46C9; Threshold; I2
Should be not greater than C/2, where C - FullChargeCapacity.

9.5.2 SEALED to UNSEALED
SEALED to UNSEALED instructs the device to extend access to the standard and extended registers and data flash space and clears the [SEC1][SEC0] flags. In UNSEALED mode, all data, standard and extended registers and DF have read/write access. Unsealing is a two-step command performed by writing the first word of the unseal key to AltManufacturerAccess() (MAC), followed by the second word of the unseal key to AltManufacturerAccess(). The unseal key can be read and changed via the MAC SecurityKey() command when in FULL ACCESS mode. To return to the SEALED mode, either a hardware reset is needed, or the MAC SealDevice() command is needed to transit from FULL ACCESS or UNSEALED to SEALED.
