@ Description
_7443_get_position():
This function is used to read the value of feedback position counter.
Note, this value has already been processed by move ratio. If move
ratio is 0.5, than the value read will be twice as the counter value.
The
source of feedback counter is selectable by function
_7443_set_feedback_src() to be external EA/EB or pulse output of
PPCI7443.
_7443_set_position():
This function is used to change the feedback position counter to the
specified value. Note, the value to be set will be processed by move
ratio. If move ratio is 0.5, than the set value will be twice as given
value.
_7443_get_command():
This function is used to read the value of command position counter.
The source of command position counter is the pulse output of
PPCI7443.
_7443_set_command():
This function is used to change the value of command position
counter.
_7443_get_error_counter():
This function is used to read the value of position error counter.
_7443_reset_error_counter():
This function is used to clear position error counter.
_7443_get_general_counter():
This function is used to read the value of general counter.
_7443_set_general_counter():
This function is used to set the counting source of and change the
