Sleep2 mode.
Field Name
Slp2_Freq[3:0]
Slp2_Etm[3:0]
Description
Each step change is equivalent to 64ms. Relative to its value 0 ~ 15, the sampling frequency time is
64ms ~ 1024ms. Default Slp2_Freq[3:0] = 1 (128ms)
Each step is equivalent to 20.48sec. Relative to its value 0 ~ 15, the entering time is 20.48sec ~
327.68sec. Default Slp2_Etm[3:0] = 0 (20.48sec)

Sleep3 mode.
Field Name
Slp3_Freq[3:0]
Slp3_Etm[3:0]
Description
Each step is equivalent to 64ms. Relative to its value 0 ~ 15, the sampling frequency time is 64ms ~
1024ms. Default Slp3_Freq[3:0] = 7 (512ms)
Each step change is equivalent to 20.48sec. Relative to its value 0 ~ 15, the entering time is 20.48sec
~ 327.68sec. Default Slp3_Etm[3:0] = 0 (20.48sec)

Data Type: Six-bit number.
Usage:
This register is the CPI resolution of sensor for X axis. Each step is equivalent to 38 counts based on x1 lens magnification.
Default value is 27 (CPI = 1026). Target CPI = 38 * CPI_X. Recommended range : 16 ~ 63 (CPI = 608 ~ 2394)
