2.14.Serial Interface
2.14.1.I
2
C-Bus Interface
Communication between the VDP and the external
controller is done via I
2
C-bus. The VDP has two
I
2
C-bus slave interfaces (for compatibility with VPC/
DDP applications) - one in the front-end and one in the
back-end. Both I
2
C-bus interfaces use I
2
C clock syn-
chronization to slow down the interface if required.
Both I
2
C-bus interfaces use one level of subaddress:
the I
2
C-bus chip address is used to address the IC and
a subaddress selects one of the internal registers. The
I
2
C-bus chip addresses are given below:
The registers of the VDP have 8 or 16-bit data size;
16-bit registers are accessed by reading/writing two
8-bit data words.
Fig. 2
–
27 shows I
2
C-bus protocols for read and write
operations of the interface; the read operation requires
an extra start condition and repetition of the chip
address with read command set.
