Detailed Description

Dynatem DPC104 VME-PC104 Bridge Interface Library.

The DPC104 VME-to-PC104 bus bridge board maps PC104 port I/O addresses into the VME A16 address space. Also, PC104 interrupts are propogated to a VME interrupt level. Each PC104 interrupt may be assigned a unique VME interrupt vector number.

#define DPC104_VME_INT_LEVEL   7

The VME bus interrupt level that propogates the PC104 interrupt levels.

#define DPC104_VME_INT_VEC_BASE   0xf0

The base interrupt vector number for all PC104 interrupts mapped to the VME bus interrupt level. For example PC104 interrupt level '3' is mapped to (DPC104_VME_INT_VEC_BASE + 3) = 0xf3.
