Programmable angle sensor
[1]
Undefined; must be written as zero for default and may return any value when read.
Values 4865 to 5120 are reserved. It is not permitted to use such values.
Examples:
100 %V
DD
= 5120 (reserved)
95 %V
DD
= 4864
90 %V
DD
= 4608
(10)
Examples:
[1]
Variable; depending on the setting of diagnostic level and slope of analog output.
(11)
Mechanical angular range 0000h = 0
to 3FFh = 180
1 LSB.
(12)
If the magnetic field angle is larger than the CLAMP_SW_ANGLE, the output switches to
CLAMP_LO for a positive slope. The value of CLAMP_SW_ANGLE can be calculated
from other non-volatile memory constants but must be programmed.
