For these registers a bus cycle will be performed on the L-bus and the U-bus with the address as shown in
Table
11.8.1
The L2U registers are accessible from the U-bus side only if it is a supervisor mode data access and the
register address is correct and it is indicated on the U-bus that it is a PPC register access.
A user mode access, or an access marked as instruction, to L2U registers from the U-bus side will cause a
data error on the U-bus.
11.8.2
All L2U registers are defined by MPC500 architecture as being 32-bit registers in normal mode. There is
no MPC500 instruction to access either a half word or a byte of the special purpose register.
All L2U registers are only word accessible (read and write) in peripheral mode. A half-word or byte access
in peripheral mode will result in a word transaction.
11.8.3
The L2U module configuration register (L2U_MCR) is used to control the L2U module operation.
