DESCRIPTION
DCS0*
DCKE
DCLKIN
This pin is used as the chip select signal for Bank0 SDRAMs.
This pin is used as the clock enable for SDRAMs.
This pin must be tied externally to the DCLKOUT signal and is used to match
skew for the data input when reading from SDRAM and DRAM devices.
This pin is the (nominal) 73.728MHz clock for the SDRAMs.
This pin is the upper data mask for a 16-bit SDRAM configuration.
This pin is the lower data mask for a 16-bit SDRAM or an 8-bit SDRAM
configuration.
These pins are the Chip Select 3 through 0 signals. They can be configured to
support either 32-bit or 16-bit ports.
These pins are the Chip Select 1 through 0 signals for the external device.
They can be configured to support either 32-bit or 16-bit ports.
These pins are the Chip Select signals for PCMCIA card slot 2.
These pins are the Chip Select signals for PCMCIA card slot 1.
This pin is the REG* signal for the PCMCIA cards.
This pin is the IORD* signal for the PCMCIA IO cards.
This pin is the IOWR* signal for the PCMCIA IO cards.
This pin is used to provide the direction control for bi-directional data buffers
used for the PCMCIA slot(s). This signal will assert whenever CARD2CSH* or
CARD2CSL* or CARD1CSH* or CARD1CSL* is asserted and a read
transaction is taking place.
This pin is the card wait signal from PCMCIA card slot 2.
This pin is the card wait signal from PCMCIA card slot 1.
This pin is the wait signal from the external device 1.
This pin is the wait signal from the external device 0.
