Description of Functions
1. Master/Slave Modes
[Relevant pins] XMST, LRCK, BCK
When connecting multiple CXD2720Q-2s, or when using as a pair with a D/A converter such as the
CXD2558M, one of the CXD2720Q-2 should be in master mode to supply LRCK and BCK.
The clock applied to LRCK and BCK in slave mode must be synchronized to either the crystal oscillator clock
of the XTLI and XTLO pins or the external clock input from the XTLI pin
