The L2U module can operate in the following modes:
11.4.1
In normal mode (master or slave) the L2U module acts as a bidirectional protocol translator.
In addition to the bus protocol translation, the L2U supports other functions such as show cycles, data
memory protection, and MPC500 reservation protocol.

Normal mode
Reset operation
Peripheral mode
Factory test mode
In master mode the RCPU is fully operational, and there is no external master access to the U-bus.
Slave mode enables an external master to access any internal bus slave while the RCPU is fully
operational. The L2U transfers load/store accesses from the RCPU to the U-bus and the read/write
accesses by the U-bus master to the L-bus.
