Tristate input/output pins. Connect these pins to an 8- or 16-bit microprocessor bus.
Microprocessor interface select pin. The S1D13305 series supports both 8080 family
processors (such as the 8085 and Z80®) and 6800 family processors (such as the 6802
and 6809).
2.7 to 5.5V supply.
This may be the same supply as the controlling microprocessor.
Ground
Crystal connection for internal oscillator (See section 13). This pin can be driven by an external
clock source that satisfies the timing specifications of the EXT 0 signal (See section 6.3.6).
