<Stop> flag allows to distinguish whether state Stopped was entered after HardStop/SoftStop or not. <Stop> is set to
‘1’ when leaving state HardStop or SoftStop and is reset during first clock edge occurring in state Stopped.
8
While in state Stopped, if ActPos ≠ TagPos there is a transition to state GotoPos. This transition has the lowest
priority, meaning that <Stop>, <TSD>, etc. are first evaluated for possible transitions.
9
If <StepLoss> is active, then SetPosition and GotoSecurePosition commands are ignored (they will not modify TagPos
register whatever the state) and motion to secure position is forbidden. Other commands like RunInit or ResetPosition
will be executed if allowed by current state. <StepLoss> can only be cleared by a GetFullStatus1 command.
5.2
RAM and OTP Memory
Some RAM registers (e.g. Ihold, Irun) are initialized with the content of the OTP (One Time
Programmable) memory. The content of RAM registers that are initialized via OTP can be changed
afterwards. This allows user initialization default values, whereas the default values are one time
programmable by the user. Some OTP bits are address bits of the TMC222.
