C-bus interface and register definitions
8.1 I
8.2 Memory page management
The I
(400 kHz) and Standard-mode (100 kHz) are supported.
The registers of the TDA9989 can be accessed via the I
except for those which are confidential.
HDMI and CEC cores I
Table 21.
Table 22.
For read access, the master writes the address of the TDA9989 HDMI or CEC core, and
the subaddress to access the specific register and then the data.
The I
between pages is made with common register CURPAGE_ADR. It is only necessary to
write in this register once to change the current page. So multiple read or write operations
in the same page need a write register CURPAGE_ADR once at the beginning.
The following memory pages are available for the TDA9989:
