The tray switch is determined according to the state where Pin 2 (PY1/MODE) and Pin 16 (PC3/KI3) is
connected immediately after reset or not.
Connected: DSP expansion port used
Not connected: Microcomputer port used
However, use the microcomputer port when the OPEN/Batt-E function is employed for portable mode.
The selected mute (Pin 2 (PY1/MODE) or Pin 15 (PC2/KI2)) is used to identify which of the CXD2507A or
CXD2508A is employed for DSP.
Therefore, select the suitable method for the used DSP.
CXD2508A: DAC mute selected
CXD2507A: DSP mute selected
