REST1_DOWNSHIFT

Address: 0x10

Rest1 to Rest2 Downshift Time Register

Access: Read/Write

Reset Value: 0x1f

Bit

76543210

Field

R1D7

R1D6

R1D5

R1D4

R1D3

R1D2

R1D1

R1D0

Data Type: Eight bit number.

USAGE: This register sets the Rest1 to Rest2 mode downshift time. Time = (register value R1D [7:0]) x (Rest1 period) x 16.

Min value for this register is 0x01.

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 10 XX  -> writing into this register

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

REST2_PERIOD

Address: 0x11

Rest2 Period Register

Access: Read/Write

Reset Value: 0x09

Bit

Field

R2P7

R2P6

R2P5

R2P4

R2P3

R2P2

R2P1

R2P0

Data Type: Eight bit number.

USAGE: This register sets the Rest2 period. Period = (register value R2P [7:0] +1) x 10 ms (typical slow clock period).

Min value for this register is 0x01. Max value is 0xFD.

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 11 XX  -> writing into this register

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