PIN FUNCTIONS
Operation of this LSI requires input of clock with frequency of 384 fs (fs : sampling frequency) or 256 fs to the XI
terminal.
Keep the XISEL terminal open when using with the 384 fs clock. (XISEL pin is pulled up internally.)
Pull down XISEL terminal to the digital ground through 4.7 k ohm resistor when using with the 256 fs clock.
The sampling frequency can be selected in the range from 32 kHz to 48 kHz.
The sampling frequency is specified with OPR register ($00). (The sampling frequency of fs = 32 or 48 kHz can be
specified only KP2V Extended mode.)
In addition, the thing that input 37MHz in XI by a maximum is possible in only through-mode.
Connect a resistor and capacitor to PLLC terminal as shown below for adjustment of PLL in the LSI.
This LSI requires initial clear at power on. The initial clear is performed by inputting "L" to /IC terminal.
