Features Not Supported
The following features are not supported by the Tsi148 VME Slave:
•
•
•
•
VME Master
The Tsi148 is VME Master when the VME Master is internally requested by the Linkage
Module to service the PCI/X Target, DMA, or Interrupts. The internal Linkage Module
arbitrates requests for each interface. Refer to
on the Linkage Module.
The Tsi148 ’s VME Master can generate the following addressing and data transfer modes :
•
•
•
•
•
•
As VME Master, Tsi148 supports Read-Modify-Write (RMW) generation, and RETRY* as a
termination from the external VMEbus slave .
The VME Master has two 4 Kbyte posted write buffers and two 4 Kbyte prefetch read buffers.
These buffers enable the VME Master to buffer two read or write transactions simultaneously.
Tsi148 provides several mechanisms to control VMEbus usage, including: time-on timer,
time-off timer, and additional release mode control (see
