 * PB_ADCGAINL      = R60 = 0x03 (3 dec)      : sets low reference of ADC
						to produce good black level
 * PB_PREADCTRL     = R32 = 0x1400 (5120 dec) : Enables global gain changes
						through R53
 * PB_ADCMINGAIN    = R52 = 0x10 (16 dec)     : Sets the minimum gain for
						auto-exposure
 * PB_ADCGLOBALGAIN = R53 = 0x10 (16 dec)     : Sets the global gain
 * PB_EXPGAIN       = R14 = 0x11 (17 dec)     : Sets the auto-exposure value
 * PB_UPDATEINT     = R23 = 0x02 (2 dec)      : Sets the speed on
						auto-exposure routine
 * PB_CFILLIN       = R5  = 0x0E (14 dec)     : Sets the frame rate
