Eight bit number
This register sets the Rest1 period. Period = (register value R1P [7:0] +1) x 7ms (typical slow
clock period). Min value for this register is 0. Max value is 0xFD.
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 80 -> write 0x80H 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
Address: 0x10
Reset Value: 0x4f
Eight bit number
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 0.
Address: 0x11
Reset Value: 0x09
