Overview of Registers
This chapter provides a detailed description of the Tsi148’s internal registers. These registers
are separated into four groups: the PCI/X Configuration Space registers (PCFS), the Local
Control and Status Registers (LCSR), the VMEbus Global Control and Status Registers
(GCSR) and the VMEbus Configuration ROM / Control and Status Registers (CR/CSR).
Registers can be accessed by the Tsi148 PCI/X Target or the VME Slave through the internal
Linkage Module.
Register Groupings
Tsi148 register space is separated into different groups within Tsi148.

Combined Register Group (CRG)
The CRG requires 4 Kbytes of address space. The address space can be mapped into PCI/X
address space using the standard PCI/X BAR (located at offsets 0x10h and 0x14h). All CRG
accesses through the PCI/X BAR pass through the PCI/X Target Interface.
