Preliminary specication
I2C-bus controlled BTSC stereo/SAP
decoder and audio processor
TDA9852
I2C-bus format to write (slave receives data)
Table 4
Explanation of I2C-bus format to write (slave receives data)
If more than 1 byte of DATA is transmitted, then auto-increment is performed, starting from the transmitted subaddress
and auto-increment of subaddress in accordance with the order of Table 5 is performed.
Table 5
Subaddress second byte after MAD
Note
1. In auto-increment mode it is necessary to insert 3 dummy data words between volume left and control 1.
