KMA199E
Programmable angle sensor
[1] Variable and individual for each device.
[2] Undefined; must be written as zero for default.
Mechanical angular range 0000h = 0 to FFFFh = 1801LSB
Examples:
• Mechanical zero angle 0 = 0000h
• Mechanical zero angle 10 =0E38h
• Mechanical zero angle 45 = 4000h
[1] Undefined; must be written as zero for default and may return any value when read.

13 and 12 DIAGNOSTIC_LEVEL; diagnostic level behavior
of analog output
00 — active LOW (in lower diagnostic range) with
driver strength of the analog output
01 — active HIGH (in upper diagnostic range)
with driver strength of the analog output
10 — reserved
11 — reserved
11 and 10 reserved; may not be changed
9 undefined
