Interrupt Acknowledge Map

The local bus distinguishes interrupt acknowledge cycles from other
cycles by placing the binary value %11 on TT1-TT0. It also specifies the
level that is being acknowledged using TM2-TM0. The interrupt handler
selects which device within that level is being acknowledged.

VMEbus Memory Map

This section describes the mapping of local resources as viewed by
VMEbus masters. Default addresses for the slave, master, and GCSR
address decoders are provided by the ENV command. Refer to Appendix
A for additional information.

VMEbus Accesses to the Local Bus

The VMEchip2 includes a user-programmable map decoder for the
VMEbus to local bus interface. The map decoder allows you to program
the starting and ending address and the modifiers that the controller
responds to.

VMEbus Short I/O Memory Map

The VMEchip2 includes a user-programmable map decoder for the GCSR.
The GCSR map decoder allows you to program the starting address of the
GCSR in the VMEbus short I/O space.
