A typical WRITE sequence for writing 16 bits to a register is shown in Figure 11. A start
bit given by the master, followed by the write address, starts the sequence. The image
sensor then gives an acknowledge bit and expects the register address to come first,
followed by the 16-bit data. After each 8-bit transfer, the image sensor sends an
acknowledge bit. All 16 bits must be written before the register is updated. After 16 bits
are transferred, the register address is automatically incremented so that the next 16 bits
are written to the next register. The master stops writing by sending a start or stop bit.
A typical READ sequence is shown in Figure 12. First the master has to write the register
address, as in a WRITE sequence. Then a start bit and the read address specifies that a
READ is about to happen from the register. The master then clocks out the register data
8 bits at a time. The master sends an acknowledge bit after each 8-bit transfer. The
register address is incremented after every 16 bits is transferred. The data transfer is
stopped when the master sends a no-acknowledge bit.
