17 / 130 page  PCI1211 GGU/PGE PC CARD CONTROLLERS SCPS033A – OCTOBER 1998 17 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 Terminal Functions (Continued) 16-bit PC Card interface control (continued) TERMINAL I/O NAME PIN NUMBER I/O TYPE FUNCTION NAME PGE GGU TYPE READY (IREQ) 132 D6 I Ready. The ready function is provided by READY when the 16-bit PC Card and the host socket are configured for the memory-only interface. READY is driven low by the 16-bit memory PC Cards to indicate that the memory card circuits are busy processing a previous write command. READY is driven high when the 16-bit memory PC Card is ready to accept a new data transfer command. Interrupt request. IREQ is asserted by a 16-bit I/O PC Card to indicate to the host that a device on the 16-bit I /O PC Card requires service by the host software. IREQ is high (deasserted) when no interrupt is requested. REG 125 B7 O Attribute memory select. REG remains high for all common memory accesses. When REG is asserted, access is limited to attribute memory (OE or WE active) and to the I/O space (IORD or IOWR active). Attribute memory is a separately accessed section of card memory and is generally used to record card capacity and other configuration and attribute information. DMA acknowledge. REG is used as a DMA acknowledge (DACK) during DMA operations to a 16-bit PC Card that supports DMA. The PCI1211 asserts REG to indicate a DMA operation. REG is used in conjunction with the DMA read (IOWR) or DMA write (IORD) strobes to transfer data. RESET 119 B9 O PC Card reset. RESET forces a hard reset to a 16-bit PC Card. WAIT 133 A5 I Bus cycle wait. WAIT is driven by a 16-bit PC Card to delay the completion of (i.e., extend) the memory or I/O cycle in progress. WE 106 C11 O Write enable. WE is used to strobe memory write data into 16-bit memory PC Cards. WE is also used for memory PC Cards that employ programmable memory technologies. DMA terminal count. WE is used as TC during DMA operations to a 16-bit PC Card that supports DMA. The PC1211 asserts WE to indicate TC for a DMA read operation. WP (IOIS16) 136 D5 I Write protect. WP applies to 16-bit memory PC Cards. WP reflects the status of the write-protect switch on 16-bit memory PC Cards. For 16-bit I/O cards, WP is used for the 16-bit port (IOIS16) function. I/O is 16 bits. IOIS16 applies to 16-bit I/O PC Cards. IOIS16 is asserted by the 16-bit PC Card when the address on the bus corresponds to an address to which the 16-bit PC Card responds, and the I/O port that is addressed is capable of 16-bit accesses. DMA request. WP can be used as the DMA request signal during DMA operations to a 16-bit PC Card that supports DMA. If used, the PC Card asserts WP to indicate a request for a DMA operation. VS1 VS2 131 117 C6 D9 I/O Voltage sense 1 and voltage sense 2. VS1 and VS2, when used in conjunction with each other, determine the operating voltage of the 16-bit PC Card. |
