Camera Control Serial Port
I I C LR ACK Mode: ( MODE= 2)
This is the IIC LRACK (Last Read Acknowledged) automatic mode, and is selected when the
MODE field (d7-d4) of the SER_MODE register is set to 2. In this mode, the IICCK frequency
is set to 93.75 KHz.

NOTE:
In both Read and Write sequence, data should be stable during the '1' state of the clock IICCK.
D7-D0 are sent by transmitter, Ack is sent by receiver.

NOTE:
Start is defined when the IICDT turns from '1' to '0' while the IICCK is '1'. Stop is defined when
the IICDT turns from '0' to '1' while the IICCK is '1'. The Address byte is written like any other byte.

In this mode, the host defines the camera address byte and the data bytes to be written to the
camera in the appropriate registers. The ZR36506 then sends these bytes automatically.
Similarly, the ZR36506 may read data bytes from the camera. The ZR36506 acknowledges the
last byte read like all other bytes.
By using the NO_STOP and CONTINUE bits, a concatenation of multiple IICC transactions is
possible, in order to send or receive more than 4 bytes in a single START / STOP frame.
Additionally, by using these control bits, write/read operations may be combined with a single
STOP pattern at the end. Note that the SER_LEN parameter may be set to 0 to further support
the concatenation operation mode.
