A typical write sequence for writing 16 bits to a register is shown in Figure 8. A start bit
given by the master, followed by the write address, starts the sequence. The image
sensor will then give an acknowledge bit and expects the register address to come first,
followed by the 16-bit data. After each eight-bit transfer, the image sensor will give an
acknowledge bit. All 16 bits must be written before the register will be 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 9. 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 eight
bits at a time. The master sends an acknowledge bit after each eight-bit transfer. The
register address should be incremented after every 16 bits is transferred. The data
transfer is stopped when the master sends a no-acknowledge bit.
