PC/104 interface
The VIPER PC/104 interface is emulated from the PXA255 PCMCIA interface to VL support 8/16 bit ISA bus style signals. As the interface is an emulation the VIPER does
not support some PC/104 features. Please refer to the Unsupported72HPC/104 interface features, page 703 3H, for specific details.
The ISA bus is based on the x86 architecture and is not normally associated with RISC processors. It is necessary to modify standard drivers to support any third party PC/104 modules.
