Measurement Register Contents
5.1.1
0x000B (read/write) – Measurement Control
Bit
Symbol
Default
Description
D15 (MSB)
– D12
r
0
(Reserved. Always set to default state)
D11
MgnRngExt
0
“Magnet Range Extension”
Only useful if Bit Gradient = 1. Enables the
algorithm for an extended position range. Refer to
chapter 7.7 for further information.
0 = Magnet Range Extension disabled
1 = Magnet Range Extension enabled
D10
CoordSel
0
“Coordinate System Selection”
Only useful if Bit MgnDir = 1. The linearized angle
can be inverted if the magnet is rotated.
0 = Linearized Angle (0x0122) is not changed
1 = The sign of the Linearized Angle (Register
0x0122) is inverted
D9
Special<1>
0
“Special Function”
Must be set to 0b11 if TableSelect=0b01. Refer to
chapter 6.2 for further explanation.
D8
Special<0>
0
D7
TableSelect<1
>
0
“Table Select”
These bits allow the selection of 4 different
operating modes. Refer to chapters 6.1 to 6.6.
D6
TableSelect<0
>
0
D5
MgnDir
0
“Magnet Direction”
This Bit allows to switch the magnet direction.
0 = Magnetic north pole must point to the directions
indicated in chapters 6.3 to 6.6.
1 = North pole must point to the opposite direction.
D4
Gradient
0
“Gradient Mode”
0 = absolute measurement of Hall sensors,
1 = differential measurement of Hall sensors.
D3 – D2
r
0
(Reserved. Always set to default state)
D1
Rdy2hZ
1
“READY to high Z State”
0 = Pin READY is always active. It must NOT be
connected in parallel with other devices.
1 = Several READY pins may be connected in
parallel. Important: READY is only set if the sensor
chip is selected with CS_N (also see chapter 7.5).
D0 (LSB)
PWMflags
0
“State flags in PWM mode”
0 = Normal operation
1 = Enables output of error flags on pins READY
(MagLost) and MISO (CalcErr), see chapter 7.4.
