OTP Register Contents:

CCW

Counter Clockwise Bit

ccw=0 – angular value increases in clockwise direction

ccw=1 – angular value increases in counterclockwise direction

Z [9:0]

Programmable Zero / Index Position

Indx

Index Pulse Width Selection: 1LSB / 3LSB

Div1,Div0

Divider Setting of Incremental Output

Md1, Md0

Incremental Output Mode Selection

OTP Default Setting

The AS5040 can also be operated without programming. The default, un-programmed setting is shown in Table 6

(Mode 0.0):

CCW: 0

= clockwise operation

Z9 to Z0: 00

= no programmed zero position

Indx: 0

= Index bit width = 1LSB

Div0,Div1 : 00

= incremental resolution = 10bit

Md0, MD1: 00

= incremental mode = quadrature
