Memory Address Bus. These are the upper eight address pins.
Reserved. This pin is reserved for future use and must be tied to GND.
Reserved. These pins are reserved for future use and must be left open.
Reserved. These pins are reserved for future use and should be left open.
Reserved. These pins are reserved for future use and must be left open.
Memory Address A15 Flip. This signal inverts the A15 address signal
for 32-Kbyte bank switching on the local memory bus.
MSM665x Strobe. This output provides the LOAD signal for an external
speech synthesizer.
ROM Page Select. These signals select one of four 64-Kbyte ROM
pages.
Reserved. This pin is reserved for future use and must be left open.
Reserved. This pin is reserved for future use and should be left open.
MSM665x Busy. When using an external MSM665x device, this pin
monitors the MSM665x BUSY signal and connects directly to the
MSM665x BUSY signal output.
MSM665x Serial Clock. This MSM6679A-110 output connects to the
MSM665x SI input. The SI pin is the MSM665x serial clock input pin.
MSM665x Serial Data. This MSM6679A-110 output connects to the
MSM665x SD input. The SD pin is the MSM665x serial data input pin.
Ground.
Reserved. This pin is reserved for future use and should be left open.
Reserved. This pin is reserved for future use and must be left open.
Load Program. This signal allows the MSM6679A-110 to write data to
program memory. When asserted low, this signal should set the
program memory in write mode.
RAM Page Select. These signals support selection of one out of four
RAM pages. Each page is 64kbytes in size.
Reserved. These pins are reserved for future use and must be left open.
Reserved. These pins are reserved for future use and should be left open.
