8.3 Demodulation Function Master/Slave Settings (
_____
CKST)
A master/slave function that allows multi-channel synchronized transfer using multiple LC89057W-VF4 LSIs is
included. This setting connects either a 10k
pull-down or a pull-up resistor to
______
CKST .
Set to the master mode normally, when single LC89057W-VF4 LSI is used. When multiple LC89057W-VF4 LSIs are
used, set one of them to the master mode and the others to the slave mode.
To transfer multi-channel synchronously using multiple LC89057W-VF4 LSIs, connect RBCK and RLRCK (output)
on the master side to RBCK and RLRCK (input) on the slave side. Also connect XMCK on the master side to XIN on
the slave side. At this time, the polarity of RBCK and RLRCK, and the frequency of XIN and XMCK must be
identical.
If the input data sampling frequency or the phase are different between the master mode and slave mode or if the
clock sources differ while the sampling frequencies are not different, some of the output data may get dropped or read
twice on the slave side. You can see if these are happening by
____
INT and the microcontroller interface.

8.4 Switching between Modulation Function and General-Purpose I/O Port (
___
INT)
The modulation function and the general-purpose I/O function share same pins. Therefore, they cannot be used
simultaneously.
To switch functions, connect either a 10k pull-down or pull-up resistor to
___
INT.
