MCU Data Bus.
Tristate input/output pins. Connect these pins to an 8- or 16-bit microprocessor bus.

MCU Interface Select.
The RA8835A series supports both 8080 family processors (such as the 8085 and
Z80®) and 6800 family processors (such as the 6802 and 6809).
SEL1 should be tied directly to VDD or VSS to prevent noise. If noise does appear on
SEL1, decouple it to ground using a capacitor placed as close to the pin as possible.

Read Control or Enable.
When the 8080 family interface is selected, this signal acts as the active-LOW read
strobe. The RA8835A series output buffers are enabled when this signal is active.
When the 6800 family interface is selected, this signal acts as the active-HIGH
enable clock.
Data is read from or written to the RA8835A series when this clock goes HIGH.
