Notes: 1. Notes on unused pins.
Unused input pins must be connected to the ground level (0 V).
Unused output pins must be left open. Do not connect anything to these pins.
Unused I/O pins may either be connected to the ground level (0 V) or set to output mode and left open.
2. The corresponding power supply levels must be provided to all of the DV

pins. The
corresponding power supply level must also be provided to DV
DD

5. (See the Allowable Operating Ranges specifications
for the supply levels.)
3. The TEST1 and TEST2 input pins must be connected to ground (0 V).
4. The I/O pins (MDAT0:15, STREQ, STCK, and STDAT) go to input mode after a reset.
5. After first applying the power supply levels, the RESB pin must be held low for at least 1 μs.
6. A 16.9344 MHz clock signal must be supplied to the CKIN pin by the CD DSP.
The LC78684E does not support the implementation of an oscillator circuit using an oscillator element.
