This bit establishes the direction of interpolation when the circular arc center
and circular arc end point are defined.

The positioning action enable bit (bit 02) determines whether a positioning
action is enabled or disabled. (Bit 03 is not used.) When positioning actions
are all enabled, they will be executed in sequence. When a positioning action
is disabled, it will be skipped, although its completion code will still be effec-
tive (see below).
Execution of disabled positioning actions depends on their completion codes.
If the completion code of the disabled action is 0 (terminating), then no posi-
tioning will take place and the address counter will be incremented. If the
completion code of the disabled action is 1 (continuous), the next positioning
action will be executed according to its parameters. Naturally, if the next posi-
tioning action is also disabled, operation will then be based on the completion
code for it. In simple terms, the completion codes of all positioning actions
are effective, even if the positioning action is disabled and no positioning is
carried out for it.
The following examples illustrates the relationship between disabled position-
ing actions and completion codes. The pertinent parameters for the position-
ing actions is as follows:
Address
Parameters
101
Incremental position, completion code of 1, enabled
102
Incremental position, completion code of 0, disabled
103
Incremental position, completion code of 0, enabled
If execution was started from address 101, the following action would result
and the address counter would end up being set to 103.
101
102
(disabled)
If the positioning action at address 102 had a completion code of 1, the fol-
lowing action would result.
101
102
(disabled)
