5.7.9 SGP (set global parameter)
With this command most of the module specific parameters not directly related to motion control can be
specified and the TMCL™ user variables can be changed. Global parameters are related to the host interface,
peripherals or application specific variables. The different groups of these parameters are organized in banks
to allow a larger total number for future products. Currently, only bank 0 and 1 are used for global
parameters, and bank 2 is used for user variables. Refer to chapter 7 for a complete parameter list.
All module settings will automatically be stored non-volatile (internal EEPROM of the processor). The
TMCL™ user variables will not be stored in the EEPROM automatically, but this can be done by using
STGP commands.
Internal function: the parameter format is converted ignoring leading zeros (or ones for negative values). The
parameter is transferred to the correct position in the appropriate (on board) device.

EEPROM magic
Setting this parameter to a different value as $E4 will
cause re-initialization of the axis and global parameters
(to factory defaults) after the next power up. This is
useful in case of miss-configuration.
