Function  
immediately  
An external counter displays the  
absolute angle following power on.  
0x01  
after 5 ms  
An external counter only displays  
changes vs. the initial power-on  
condition (moving halted to  
reapply power is precondition.)  
Notes  
*) Output delay after device configuration and  
internal reset.
