MICROPROCESSOR PORT
Address Bit 0. Address bit 0 of the microprocessor interface. Least
Significant Bit. Note that the parallel bus is not available in the 144 pin
DS33X11, and the SPI Slave port must be used for processor control.
Address Bit 1. Address bit 1 of the microprocessor interface.
Address Bit 2. Address bit 2 of the microprocessor interface.
Address Bit 3. Address bit 3 of the microprocessor interface.
Address Bit 4. Address bit 4 of the microprocessor interface.
Address Bit 5. Address bit 5 of the microprocessor interface.
Address Bit 6. Address bit 6 of the microprocessor interface.
Address Bit 7. Address bit 7 of the microprocessor interface.
Address Bit 8. Address bit 8 of the microprocessor interface.
Address Bit 9. Address bit 9 of the microprocessor interface.
Address Bit 10. Address bit 10 of the microprocessor interface.
Data Bit 0. Bi-directional data bit 0 of the microprocessor interface. Least
Significant Bit. Not driven when CS=1 or RST=0.
SPI_MISO (SPI_SEL=1). SPI Serial Data Output (Master-in Slave-Out).
Data Bit 1. Bi-directional data bit 1 of the microprocessor interface. Not
driven when CS=1 or RST=0.
SPI_MOSI (SPI_SEL=1). SPI Serial Data Input (Master-out Slave-in)
Data Bit 2. Bi-directional data bit 2 of the microprocessor interface. Not
driven when CS=1 or RST=0.
SPI_CLK (SPI_SEL=1). SPI Serial Clock Input.
Data Bit 3. Bi-directional data bit 3 of the microprocessor interface. Not
driven when CS=1 or RST=0.
Data Bit 4. Bi-directional data bit 4 of the microprocessor interface. Not
driven when CS=1 or RST=0.
