Data bus I/O control block
The data bus (D0 to D15) can be controlled with two control signals: IOCNT1 and IOCNT2.
These pins must be held low if unused.
CPU Connection example <CCB Interface>
* SCK, TX, and RX are the CPU serial interface channel. Normally, I/O port pins may be used for these lines.
* The resistance of the DO pin pull-up resistor must be selected according to the transfer clock speed.
