Description

Control Register 1

LP_pulsed

1 R/W 0x76

1

<7> Low Power control register. See Table 2.

LP_active

1 R/W 0x76

0

<6> Low Power control register. See Table 2.

LP_continue

1 R/W 0x76

0

<5> For test only. Must be 0.

Interrupt control register.

INT_wup_en

1 R/W 0x76

1

<4>

If set, the interrupt pin goes low in Shutdown mode when

the magnet has moved away from the center, above the

xp, xn, yp yn threshold values.

Interrupt control register.

INT_act_en

1 R/W 0x76

1

<3>

If set, the interrupt pin goes LOW in Low Power mode

when a new XY value is ready for reading. Stores

coordinate until next read in full power mode,

ext_clk_en

1 R/W 0x76

0

<2> For test only. Must be 0.

Soft Reset.

soft_rst

1 R/W 0x76

0

<1>

soft_rst = 0: normal mode

soft_rst = 1: all registers return to their respective reset

value

Data valid.

data_valid

1 R 0x76

0

<0> data_valid = 0: no valid XY coordinates

data_valid = 1: valid data are ready to be read

Control Register 2

Test 7

1 R/W 0x75

0

<7> For test only. Must be 0.

Test 6

1 R/W 0x75

1

<6> For test only. Must be 1.

Test 5

1 R/W 0x75

0

<5> For test only. Must be 0.

Test 4

1 R/W 0x75

0

<4> For test only. Must be 0.

ext_sample_en 1 R/W 0x75

0

<3> For test only. Must be 0.

rc_bias_on

1 R/W 0x75

0

<2> For test only. Must be 0.

inv_spinning

1 R/W 0x75

0

<1>

Invert the channel voltage.

Set if the magnet polarity is reversed.

pptrim_en

1 R/W 0x75

0

<0> For test only. Must be 0.

Range and position values

Xp

8 R/W 0x43 2’ comp

0x28

(40d)

Wakeup threshold on the positive X direction.

Xn

8 R/W 0x44 2’ comp

0xD8

(-40d)

Wakeup threshold on the negative X direction.

Yp

8 R/W 0x53 2’ comp

0x28

(40d)

Wakeup threshold on the positive Y direction.

Yn

8 R/W 0x54 2’ comp

0xD8

(-40d)

Wakeup threshold on the negative Y direction.

X

8 R 0x41 2’ comp 0x00

X position. The zero value means the horizontal center

position on the AS5011.

Y

8 R 0x42 2’ comp 0x00

Y position. The zero value means the vertical center

position on the AS5011.

X_res_int

8 R 0x51 2’ comp 0x00

X position. Releases INT_n to ‘1’

Y_res_int

8 R 0x52 2’ comp 0x00

Y position. Releases INT_n to ‘1’
