CPC945 Bridge and Memory Controller
2.1.6 HyperTransport Bridge
The HyperTransport bridge carries external interrupt information between a HyperTransport southbridge
device and the CPC945. It has the following features:
• Provides 64-byte memory accesses through a 16-bit-wide bus.
• Bridges to HyperTransport-capable southbridge or I/O devices.
• Maps boot ROM through the HyperTransport bus.
• Carries external interrupt information between a HyperTransport southbridge and the CPC945.
