Bit 7
Address: 0x35
Reset Value: 0xf0
Eight bit unsigned integer.
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 0xf0, the typical frame rate is about 2250 fps @26MHz
Address: 0x3a
Reset Value: 0x00
Eight bit unsigned integer.
This register is used as chip reset by writing 0x5a into this register.
Address: 0x3f
Reset Value: 0xfe
Eight bit unsigned integer
This register contains the inverse of the revision ID which is located at register 0x01.
