For these registers a bus cycle will be performed on the L-bus and the U-bus with the
address as shown
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.
All L2U registers are defined by PowerPC architecture as being 32-bit registers. There
is no PowerPC 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.
The L2U module configuration register (L2U_MCR) is used to control the L2U module
operation.
