10. Description of Modulation Function and General-Purpose I/Os
10.1 How to use Modulation function
10.1.1 Initial setting
The modulation function and general-purpose I/O port function cannot be used simultaneously because they share the
same pins. To select the modulation function, pull down
______
INT with a 10k
resistor. For further information about the
setting, see Chapter 8.
In the initial setting, the modulation function is stopped. To apply the modulation function, set it with TXOPR.
10.1.2 Data output (TMCK, TBCK, TLRCK, TDATA, TXO)
Bi-phase modulated data is output from TXO by inputting a 256fs clock to TMCK, 64fs clock to TBCK, fs clock to
TLRCK, and audio data to TDATA.
The polarity of the TLRCK clock is set with TXLRP.
Input data can be modulated in the sampling range of 32kHz to 192kHz, in the transfer rate of 4MHz to 25MHz, and
up to 24-bit data.
The initial value for the input data format is set in I2S. Switching to MSB-first right-adjusted input is set with TXDFS.
For the channel status, the first 48 bits of data can be written with the microcontroller interface.
TXO is fixed to "L" by setting TXOPR to Stop or TXMUT.
