BENTLY 3500/15 106M1079-01 Power supply module

Setting the Short I/O Base Address The 1 Kbyte block of short address space occupied by the card is located on a 1 Kbyte boundary at an address selected by positions 1 through 6 of the switch. These switch positions correspond to address bits A15 through A10, respectively. Therefore, when all switches are ON, the base address is 0000 and the card responds to short space addresses 0001, 0003, 0005, 0007, and 0009 

Supervisory or non-privileged accesses may be made to short address space (2Dh and 29h respectively). An access to the card with an address modifier code that is not supported causes a VMEbus error. Position 7 of the card's DIP switch selects whether only supervisory accesses or both supervisory and non-privileged accesses are permitted. The following table shows the switch positions.

Access Privileges

 The 5136-PFB-VME provides 8-bit access to objects in the short address space and 8- and 16-bit access to objects in the standard address space. The VME master selects whether a particular bus cycle accesses short, standard, extended, or long (extended and long are not used on the 5136-PFB-VME) address spaces, and the type of access, through the use of the address modifier codes. The card decodes these address modifier codes and determines the object to be accessed. In addition to selecting one of four spaces available on the VMEbus, address modifier codes also select: • whether the master is making a supervisory or non-privileged access • whether the access is to program or data space (for all but short address space accesses) • whether it is to be a single-object or block access The 5136-PFB-VME can respond to address modifier codes 3Dh, 39h, 2Dh, and 29h. Supervisory or non-privileged data accesses may be made to standard address space (3Dh and 39h respectively). 

Interrupts

 The card can generate and acknowledge interrupts on any one of VMEbus interrupt lines 1 through 7, (or none). The interrupt level is selected by positions 8 through 10 of switch S1, as detailed below:The card interrupter is a ROAK (release-on-acknowledge) type. The interrupt request is removed from the VMEbus when the card responds to an interrupt acknowledge. However, the CpuIntVme bit in the Interrupt Control register remains set until cleared by the host.

The 5136-PFB-VME is shipped with all switches ON. This corresponds to: • short I/O address 0000 • supervisory and non-privileged access permitted • interrupts disabled 2.5 Setting the Jumpers Set the jumpers on the 5136-PFB-VME before installing the card in a VMEbus computer. These jumpers control various aspects of the card operation.
