(1-2) Evaluation of Playback block (HP, LINEOUT) using DIR of AK4114
PORT1 (DIR) is used. Nothing should be connected to PORT2 (DIT), PORT3 (DSP) and J11 (EXT). The jumper
pins should be set to the following.

When AK4114 is used, JP22 (MKFS) and JP23 (BCFS) are not used. Therefore, JP22 (MKFS) should be set to
“x1” and JP23 (BCFS) should be set to “64fs”.
* The AK4114 operates at fs of 32kHz or more. If the fs is slower than 32kHz, this evaluation mode can’t be used.
(1-3) Evaluation of Loop-back using AK4114
X’tal oscillator (X1) is used. Nothing should be connected to PORT1 (DIR), PORT3 (DSP) and J11 (EXT). The
jumper pins should be set to the following.
