0x00 PWM_FREQ

0x00 PWM_SENS

PWM output frequency (RW)(4 MSBs are reserved):

n = 0 to 15

fPWM = fOSC * 2n-18, where fOSC = 3.6 MHz.

PWM sensitivity (RW)(3 MSBs are reserved):

n = 0 to 26

0 = high sensitivity, 26 = low sensitivity. Practical values lie between 9

and 18. Refer to Figure 4: PWM duty cycle versus illumination for

typical behavior.
