AMIS ? 30621
A hardstop command can also be issued by the LIN master for some safety reasons. It corresponds then to the following
two data bytes LIN writing frame (type #1).

( * ) According to parity computation
Broad: If broad = ‘0’ all stepper motors connected to the LIN bus will stop
ResetPosition
This command is provided to the circuit by the LIN master
to reset <ActPos> and <TagPos> registers to zero. This
can be helpful to prepare for instance a relative positioning.
Note : The dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer, i.e. ‘0000’.
The command is decoded only from the command data.
The reset position command sets the internal flag
“Reference done”.
ResetPosition corresponds to the following LIN writing frames (type #1).

ResetToDefault
This command is provided to the circuit by the
LIN Master in order to reset to whole slave note into the
initial state. ResetToDefault will, for instance, overwrite the
RAM with the reset state of the registers parameters (See
RAM Registers). This is another way for the master to
initialize a slave node in case of emergency, or simply to
refresh the RAM content.
Note: the dynamic ID allocation has to be assigned to
‘General Purpose 2 Data bytes’ ROM pointer, i.e. ‘0000’.
The command is decoded only from the command data.
