Note: Bits that are underlined are read only, all other bits are read-write; default value for all bits is 0.
Bit 0 / Factory Test (FT).
This bit is used by the factory to place the DS3134 into the test mode. For normal device operation, this
bit should be set to zero whenever this register is written to. Setting this bit places the RAMs into a low
power standby mode.
Bit 1 to 15 / Device internal test bits. Bits 1 to 15 shown in the above table is for CHATEAU internal
(Dallas Semiconductor) tests use, not user test mode controls. Values of these bits should always be “0”.
If any of these bits are set to “1” device will not function properly.
