Data Sheet
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
