setting home_mode parameter in set_home_config() function. The
meaning of Home_mode will be described as the following:
CAUTION
Due to differences between the motion chipsets of PCI-8134 and PCI-
8134A, behaviour of home mode 0 and 1 will be inconsistent as
performed previously. Please note differences in timing charts of
each home mode for both PCI-8134 and PCI-8134A when user
wants to use PCI-8134A instead of PCI-8134 with same home
function. To ensure the accuracy of home move process, the
motion chipset on PCI-8134A commands backward motion and
stops at the edge of ORG or EZ precisely.
