REST2_DOWNSHIFT

Address: 0x12

Rest2 to Rest3 Downshift Time Register

Access: Read/Write

Reset Value: 0x2f

Bit

76543210

Field

R2D7

R2D6

R2D5

R2D4

R2D3

R2D2

R2D1

R2D0

Data Type: Eight bit number.

USAGE: This register sets the Rest1 to Rest2 mode downshift time. Time = (register value R2D [7:0] ) x (Rest2 period) x

128. 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 12 XX  -> writing into this register

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

REST3_PERIOD

Address: 0x13

Rest3 Period Register

Access: Read/Write

Reset Value: 0x31

Bit

76543210

Field

R3P7

R3P6

R3P5

R3P4

R3P3

R3P2

R3P1

R3P0

Data Type: Eight bit number.

USAGE: This register sets the Rest3 period. Period = (register value R3P [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 13 XX  -> writing into this register

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