This register sets the Rest1 time period in seconds. Min value for this register is 0. Max value is 0xFD.
Rest 1 Period = (Register value (decimal) +1) x 0.007
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.
i.

iii.
This register sets the Rest1 to Rest2 mode downshift time.
Rest 1 Downshift Time = (Register value (decimal) x (Rest1 period) x 16. Min value for this register is 0.
This register sets the Rest2 period in seconds. Min value for this register is 0. Max value is 0xFD.
Rest 2 Period = (Register value (decimal) +1) x 0.007
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.
i. Write 0x80 to register 0x22H prior to writing into this register
ii. Writing the desired value to this REST2_PERIOD register
iii. Write 0x00 to register 0x22H after to writing into this register
