5.1.3 Features
The following list summarizes the key features of the PBRIDGE:
• Supports the slave interface signals. This interface is only meant for slave peripherals.
• Supports 32-bit slave peripherals. (Byte, halfword, and word reads and write are supported to
each.)
• Supports a pair of slave accesses for 64-bit instruction fetches.
• Provides configurable per-module write buffering support.
• Provides configurable per-module and per-master access protections.
5.1.4 Modes of Operation
The PBRIDGE has only one operating mode.
