Compliance Notation Description
Bus Master Compliance Levels
D08(EO) 8-bit data path from MXIbus
D16 & D08(EO) 8-bit or 16-bit data path from MXIbus
D32 32-bit data path from MXIbus
A16 Generates 16-bit short I/O addresses when specified
by the MXIbus address modifier lines
A24 Generates 24-bit memory addresses when specified
by the MXIbus address modifier lines
A32 Generates 32-bit memory addresses when specified
by the MXIbus address modifier lines
BLT Generates block mode transfers when specified

RMW Can generate Read-Modify-Write cycles
Interrupter Compliance Levels
I(7-1) Can generate an interrupt request on interrupt lines
IRQ7 through IRQ1
D16 & D32 Responds to 16-bit and 32-bit interrupt acknowledge
cycles by providing a 16-bit Status/ID byte on D00
through D15
ROAK Releases its interrupt request line when its Status/ID
is read during an interrupt acknowledge cycle
Interrupt Handler Compliance Levels
IH(7-1) Can generate interrupt acknowledge cycles in
response to interrupt requests on IRQ7 through IRQ1
D16 Generates a 16-bit interrupt acknowledge cycle in
response to a VMEbus interrupt request
