Note:
Bits that are underlined are read-only; all other bits are read-write.
Bit 0/Factory Test (FT). This bit is used by the factory to place the DS3131 into the test mode. For normal device
operation, this bit should be set to 0 whenever this register is written to.
Bit 1 to 15/Device Internal Test Bits. Bits 1 to 15 shown in the above table are for BoSS internal (Dallas
Semiconductor) test use, not user test-mode controls. Values of these bits should always be 0. If any of these bits
are set to 1 the device does not function properly.
