DDC INTERFACE
The basic DDC unit consists of an I
2
C interface
and 256 bytes of SRAM for DDC data storage. The
8032 core is responsible of loading the contents of
the SRAM with the DDC data. The DDC unit has
the following features:
I
Supports both DDC1 and DDC2b Modes.
I
Features 256 bytes of DDC data - initialized by
the 8032
I
Supports fully automatic operation of DDC1 and
DDC2b Modes
I
DDC operates in Slave Mode only.
I
SW Interrupt Mode available (existing design)
The interface signals for the DDC can be mapped
to pins in Port 4. The interface consists of the stan-
dard V
SYNC
(P4.2), SDA (P4.0) and SCL (P4.1)
DDC signals. The conceptual block diagram is il-
lustrated in Figure 43.
