VME Master
The VME Master provides the interface from Linkage Module to the VMEbus. The VME
Master can generate A16, A24, A32, and A64 VMEbus address cycles and D8 even, D8 odd,
D16, D32, and D64 data transfers. The VME Master generates transfers using the SCT, BLT,
MBLT, 2eVME, and 2eSST protocols. The VME Master supports the VMEbus RETRY_
signal.
Addressing Capabilities
The Tsi148's VMEbus addressing mode is controlled by programming the Outbound
Translation Attribute registers (see
generating A16, A24, A32, A64, and CR/CSR address phases. The address mode and type
(supervisor and program) are also programmed through the Outbound Translation Attribute
registers.
The address and Address Modifier (AM) codes that are generated by the Tsi148 are functions
of the mapping of the PCI/X memory space as defined above or through DMA programming
(see
codes used for the VMEbus.
