This register is used to confi gure the LED precharge of the sensor. The default pre fl ash is about 190uS for
nominal clock of 26MHz~28Mhz.
This register is used to control the frame rate. The value in this register is used to add frame idling time, which
eff ectively reduces the frame rate.
frame_idle_time (in clock counts) = (register value) * 32
Frame period (in clock counts) = shutter_time (reg 0x06 and reg 0x07) + (3400 clocks) + frame_idle_time
When this register is set to 0x00, the maximum frame rate is about 6666 fps @26MHz internal clock frequency
This register is used to confi gure the resolution of the sensor.
This register contains the inverse of the revision ID which is located at register 0x01.
