RUN_DOWNSHIFT

Address: 0x0e

Run to Rest1 Time Register

Access: Read/Write

Reset Value: 0x08

RUD1

RUD0

Data Type: Eight bit number.

USAGE: This register sets the Run to Rest1 mode downshift time. The time is the value of this register multiply by 8 times

of position mode period.

Default downshift time = 8 * 8 * 4 = 256 ms

NOTE:

Writing into this register when the sensor itself is operating in this rest mode may result in unexpected behavior

of the sensor. To avoid this from happening, below commands should be incorporated prior and after the write

command into this register.

w 22 40  -> write 0x40H into register 0x22H prior to writing into this register

w 0e XX  -> writing into this register

w 22 00  -> write 0x00H into register 0x22H after writing into this register

Data Type: Eight bit number.

USAGE: This register sets the Rest1 period. Period = (register value R1P [7:0] +1) x 10 ms (typical slow clock period).

NOTE:

Writing into this register when the sensor itself is operating in this rest mode may result in unexpected behavior

of the sensor. To avoid this from happening, below commands should be incorporated prior and after the write

command into this register.

w 22 40  -> write 0x40H into register 0x22H prior to writing into this register

w 0f XX  -> writing into this register

w 22 00  -> write 0x00H into register 0x22H after writing into this register
