7.3.4 LVD SCSI 68-pin Connector
Each
Table 46. LVD SCSI Connector Signal Description
Signal | Type | Driver | Name and Description |
LVD_DB[15..0]_[P, N] | I/O | LVD hs | SCSI data bus. The data bits for the differential SCSI bus. |
|
|
|
|
LVD_DBP_[P, N] | I/O | LVD hs | SCSI data parity. Support parity on the SCSI bus. DB_P0[P/N] supports |
LVD_DBP1_[P, N] |
|
| parity for data [7..0]. DB_P1[P/N] supports parity for data [15..8]. |
|
|
| |
|
|
|
|
DIFFSENSE | I | Analog | Differential sense. The voltage level determines the operating mode of |
|
|
| the target devices on the SCSI bus. If the voltage on the DIFFSENSE |
|
|
| signal is from |
|
|
| to 1.9 V the mode will be LVD. |
|
|
|
|
LVD_ATN_[P, N] | I/O | LVD hs | SCSI bus attention. Asserted by a SCSI device in initiator mode to alert |
|
|
| the target that the initiator has a message to transfer. |
|
|
|
|
LVD_BSY_[P, N] | I/O | LVD hs | SCSI bus busy. Indicate that the SCSI bus is being used. Can be driven |
|
|
| by both the initiator and the target device. |
|
|
|
|
LVD_ACK_[P, N] | I/O | LVD hs | SCSI bus acknowledge. Driven by an initiator, indicating an |
|
|
| acknowledgement for a SCSI data transfer. |
LVD_RST_[P, N] | I/O | LVD hs | SCSI bus reset. Indicate a SCSI bus reset condition. |
|
|
|
|
LVD_MSG_[P, N] | I/O | LVD hs | SCSI bus message phase. Driven by a SCSI target to indicate it is in the |
|
|
| Message Phase. |
|
|
|
|
LVD_SEL_[P, N] | I/O | LVD hs | SCSI bus select. Used by an initiator to select a target or by a target to |
|
|
| reselect an initiator. |
|
|
|
|
LVD_CD_[P, N] | I/O | LVD hs | SCSI bus control/data phase. Driven by a target, these pins indicate that |
|
|
| control or data information is being transferred over the SCSI bus. |
|
|
|
|
LVD_REQ_[P, N] | I/O | LVD hs | SCSI bus request. Driven by a target, these pins indicate a request for a |
|
|
| SCSI |
