If bit 7 = 1, then find flying measurement request applies:
0 Function 1
1 Function 2
2 Function 3
3 Function 4
Note:
Bit x = 1
•
Bit x = 0
The following applies if more than 1 function is activated:
•
The values for all functions cannot be read until each activated function
has terminated and this has been confirmed in the corresponding status
bit (ZSW.0/.1/.2/.3 "0" signal again).
Find reference mark
•
It is possible to search for a reference mark.
Equivalent zero mark
•
Flying measurement
•
Positive and negative edges can be simultaneously selected.
Command Bit 6, 5, 4
(x: function selected using bit 0 to 3)
Mode 1 Flying measurement (fine resolution via p0418)
