L-Bus to U-Bus Interface (L2U)
Table 11-4
11.8
The L2U control registers control the L2U bus interface and the DMPU. They are accessible via the mtspr
and mfspr instructions. They are also accessible by an external master when EMCR[CONT] bit is cleared.
L2U control registers are accessible from both the L-bus side and the U-bus side in one clock cycle. As
with all SPRs, L2U registers are accessible in supervisor mode only.
Any unimplemented bits in L2U registers return 0’s on a read, and the writes to those register bits are
ignored.

Name
The L2U does not provide show cycle for any L-bus addresses that fall in the L-bus CALRAM
address space if the CALRAM protection [SP] bit is set in the L2U_MCR.

summarizes the L2U show cycle support.
Case
L-bus slave includes all address in the L-bus address space.
X indicates don’t care conditions.
There will be a 1-clock turnaround because the L-bus retry information is not available in time to
negate the L-bus arbitration.
L2U indicates L2U registers.
U-bus/E-bus refers to all destinations through the L2U interface.
