4 / 5 page Signal Direction Description VME_DS1_N Input VME Data Strobe 1: Active low signal used for the selected location part of the data. VME_WRITE_N Input VME Read/Write: Active low signal which is used by the master to indicate the data direction. VME_BERR_N Input VME Bus Error: Active low signal driven by other modules indicating that the data transfer was unsuccessful. VME_IACK_N Input VME Interrupt Acknowledge: When driven low, the VME_IACKIN_N causes the IACK daisy-chain driver, located in slot 1, to propagate a falling edge down the interrupt acknowledge daisy-chain. VME_IACKIN_N Input VME Interrupt Acknowledge Input Daisy-Chain: This active low signal is used as input of the module for the daisy-chain interrupt acknowledge. VME_IACKOUT_N Output VME Interrupt Acknowledge Output Daisy-Chain: This active low signal is used as output of the module for the daisy-chain interrupt acknowledge. VME_IRQ_N[6:0] Output VME Interrupt Request Lines: Interrupters request interrupts by driving an interrupt request line low. VME_IRQ_N[7] has the highest priority. These signals have to be connected to open collector drivers. INT_USER_ADDR[31:1] Output Registered VME Address Bus: Synchronized on the falling edge of VME_AS_N. This bus is used to decode the address and to active an access signal on the user part. INT_USER_AM[5:0] Output Registered VME Address Modifier Bus: Synchronized on the falling edge of VME_AS_N. This bus is used to decode the address modifier and to active an access signal on the user part. USER_ACCESS Input User Access Signal: The user has 50 ns time to decode the address and asserting the USER_ACCESS signal when addressed. USER_ACC_REQ Output User Access Request: Active high signal which requests for an access on the VME bus. Valid until USER_ ACC_RDY acknowledges the request (or VME bus error occurs). USER_ACC_RDY Input User Side Acknowledgement Signal: Acknowledge the request of the access on the VME bus of the user part. USER_ADDR[31:1] Output User Address: Address used for the access on the user part. USER_AM[5:0] Output User Address Modifier: Address modifier used for the access on the user part. USER_WR_DATA[31:0] Output User Write Data: The data[31:24] are valid while USER_BE4 is high, data[23:16] while USER_BE3, data[15:8] while USER_BE2 and data[7:0] while USER_BE1. USER_RD_DATA[31:0] Input User Read Data: The read data has to be valid when USER_ACC_RDY is high. USER_RW_N Output User Read/Write Signal: A low signal indicates that the data are written in the user part and a low signal, that the data are read. USER_BE1 Output User Byte 1 Enable: Active high signal enabling the low byte [7:0] of the data. USER_BE2 Output User Byte 2 Enable: Active high signal enabling the high byte [15:8] of the data. USER_BE3 Output User Byte 3 Enable: Active high signal enabling the high byte [23:16] of the data. USER_BE4 Output User Byte 4 Enable: Active high signal enabling the high byte [31:24] of the data. USER_IREQ Input User Interrupt request: This active high signal indicates that an interrupt is pending on a VME interrupt will be generated. It will return to zero with USER_IACK active. USER_IACK Output User Interrupt Acknowledge: An active one event which indicates the end of a valid interrupt acknowledge cycle. USER_ILEV[2:0] Input User Interrupt Level: This bus indicates the level of priority of the pending interrupt. It will generate the corresponding VME_IRQ. USER_IVEC[31:0] Input User Interrupt Vector: The interrupt vector will be transmitted on the VME data bus during the acknowledgement of the interrupt. Table 2: VME Core Signal List |
