TABLE 3-7: HOST BUS PIN DESCRIPTIONS Num Pins Name Symbol Buffer Type Description 1 Read RD VIS This pin is the host bus read strobe. Normally active low, the polarity can be changed via the HBI Read, Read/Write Polarity bit of the PDI Configuration Register (HBI Modes). Read or Write RD_WR VIS This pin is the host bus direction control. Used in conjunction with the ENB pin, it indicates a read or write operation. The normal polarity is read when 1, write when 0 (R/ nW) but can be changed via the HBI Read, Read/ Write Polarity bit of the PDI Configuration Register (HBI Modes). 1 Write WR VIS This pin is the host bus write strobe. Normally active low, the polarity can be changed via the HBI Write, Enable Polarity bit of the PDI Config- uration Register (HBI Modes). Enable ENB VIS This pin is the host bus data enable strobe. Used in conjunction with the RD_WR pin it indicates the data phase of the operation. Normally active low, the polarity can be changed via the HBI Write, Enable Polarity bit of the PDI Config- uration Register (HBI Modes). 1 Chip Select CS VIS This pin is the host bus chip select and indicates that the device is selected for the current transfer. Normally active low, the polarity can be changed via the HBI Chip Select Polarity bit of the PDI Configu- ration Register (HBI Modes). 5Address A[4:0] VIS These pins provide the address for non-multiplexed address mode. In 16-bit data mode, bit 0 is not used. |
