START
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 sensor
then gives an acknowledge bit and expects the register address to come first, followed by
the 16-bit data. After each 8-bit the image sensor gives 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 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 8 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.
