DIO; and a controller subsystem module which employs a Data Transfer Bus Arbiter, a Subsystem Clock driver, a System Reset driver, and a Bus time- out module. (The XYCOM XVME-010 System Resource Module provides a controller subsystem with the components listed.) - Page 13 Interface Block). The base address decoding scheme for XYCOM I/O modules is such that the starting address for each I/O Interface Block resides on a 1K boundary. Thus the module base address may be set to any one of 64 possible 1K boundaries within the Short I/O Address space.
- Page 16 XVME-240 Manual October, 1984 2.4.2 Address Space Selection The user is given the option of placing the DIO in VMEbus Short I/O or Standard Memory Space. The selection is made by configuring jumper J2 and Switch 8 of Switch Bank 2 (see Figure 2-3) as shown in Table 2-3 below.
- Page 17 XVME-240 Manual October, 1984 2.4.3 Supervisor/Non-Privileged Mode Selection The DIO can be configured to respond to only Supervisory access, or to both Non- Privileged and Supervisory accesses, by selecting the position of Switch 7 (located in Switch Bank 2, see Figure 2-3), as shown in Table 2-4 below.

Therefore, jumper Jl is hardwired in position “ B " to enable the IACKIN*/IACKOUT* daisy chain. CAUTION The jumper shorting IACKIN* to IACKOUT* for the DIO’s slot in the backplane must be removed, or the...
