7.2 VPB0 bridge
Section 7.2
specifies the interfaces and function of the VPB0 bridge. The VPB0 bridge
acts as a bridge between a range of RTG IP blocks using the VPB bus and the EPICS7B
DIO interface. Two bridges are used one to connect to several slow blocks and an
additional one specifically for the UART.
The VPB0 bridge forms the bridge between the EPICS7B and the clock generation unit,
SRI I
2
C-bus, watchdog timer, event router, I/O configuration and the audio configuration
respectively.
