A typical write sequence for writing 16 bits to a register is shown in Figure 9. A start bit
given by the master, followed by the write address, starts the sequence. The image sen-
sor will then give an acknowledge bit and expects the register address to come first, fol-
lowed by the 16-bit data. After each 8-bit the image sensor will give an acknowledge bit.
All 16 bits must be written before the register will be updated. After 16 bits are trans-
ferred, 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 10. 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 8-bit transfer. The register
address is auto-incremented after every 16 bits is transferred. The data transfer is
stopped when the master sends a no-acknowledge bit.
