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

Example for resolution 64
(SELRES = 0x0A), zero signal at 0°
(ZPOS = 0x00, CFGAB = 0x00) and the
direction of rotation not inverted (ROT =
0x00, COS leads SIN).
