Display Data Channel Interfaces (DDC)

Read and Write Operations
After each byte transfer, the internal address counter automatically increments. If the counter is
pointing to the top of the structure, it rolls over to the bottom since the increment is performed only
on the 7 or 8 LSBs of the pointer depending on the selected data structure size. It rolls over from
7Fh to 00h or from FFh to 80h depending on the MSB of the last data address received.
Then after that last byte has been effectively written or read in RAM at LSB address 7Fh or FFh, the
EDF flag is set and an interrupt is generated if EDE is set.
The transfer is terminated by the master generating a STOP condition.

DDC/CI Factory Alignment Interface
Refer to the CR, SR1 and SR2 registers in
Section 11.7: Register Description
for the bit definitions.
The DDC/CI interface works as an I/O interface between the microcontroller and the DDC2Bi,
HDCP, E-DDC or Factory alignment protocols. It receives and transmits data in Slave I2C mode
using an interrupt or polled handshaking.
The interface is connected to the I2C bus through a data pin (SDAD) and a clock pin (SCLD)
configured as an open-drain output.
The DDC/CI interface has five internal register locations. Two of them are used to initialize the
interface:
1. 2 Own Address Registers OAR1 and OAR2
2. Control register CR
The following four registers are used during data transmission/reception:
1. Data Register DR
2. Control Register CR
3. Status Register 1 SR1
4. Status Register 2 SR2
The interface decodes an I2C or DDC2Bi address stored by software in either OAR register and/or
the DDC/CI address (6Eh/6Fh) as its default hardware address.
After a reset, the interface is disabled.
11.5.1 I2C Modes
The interface operates in Slave Transmitter/Receiver modes.
The master generates both Start and Stop conditions. The I2C clock (SCL) is always received by the
interface from a master, but the interface is able to stretch the clock line.
The interface can recognize its two programmable addresses (7-bit) and its default hardware
address (DDC/CI address: 6Eh/6Fh). The DDC/CI address detection may be enabled or disabled by
software. It never recognizes the Start byte (01h) whatever its own address is.
Slave mode
As soon as a start condition is detected, the address is received from the SDA line and sent to the
shift register where it is compared to the programmable addresses or to the DDC/CI address (if
selected by software).
Address not matched
: the interface ignores it and waits for another Start condition.
Address matched
: the following events occur in sequence:
