15.2.9. RAM Registers
Table 19: RAM Registers
Note 1 : A ResetToDefault command will act as a reset of the RAM content, except for ActPos and TagPos registers that are not modified.
Therefore, the application should not send a ResetToDefault during a motion, to avoid any unwanted change of parameter.
