DDC interface
The basic DDC unit consists of an I
storage. The 8032 core is responsible of loading the contents of the SRAM with the DDC
data. The DDC unit has the following features:
●
●
●
●
●
The interface signals for the DDC can be mapped to pins in Port 4. The interface consists of

Figure 39. DDC interface block diagram
Special Function register for the DDC interface
There are eight SFR in the DDC interface:
●
●
Supports both DDC1 and DDC2b modes
Features 256 bytes of DDC data - initialized by the 8032 core
Supports fully automatic operation of DDC1 and DDC2b modes
DDC operates in Slave mode only
SW Interrupt mode available (existing design)
RAMBUF, DDCCON, DDCADR, DDCDAT are DDC registers.
