I2C-bus interface and register denitions
8.1 I2C-bus protocol
The I2C-bus pins CSDA and CSCL are 1.8 V and 3.3 V tolerant. Both Fast-mode
(400 kHz) and Standard-mode (100 kHz) are supported.
The registers of the TDA9989 can be accessed via the I2C-bus. All registers are R/W
except for those which are condential.
For read access, the master writes the address of the TDA9989 HDMI or CEC core, and
the subaddress to access the specic register and then the data.
8.2 Memory page management
The I2C-bus memory is split into several pages for HDMI core only, and the selection
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:
Page 00h: general control
Page 02h: PLL settings
Page 09h: EDID control page
Page 10h: information frames and packets
Page 11h: audio settings and content info packets
Page 13h: gamut-related metadata packets
