L-Bus to U-Bus Interface (L2U)
11.8.4
The L2U region base address register (L2U_RBAx) defines the base address of a specific region protected
by the data memory protection unit. There are four registers (x = 0...3), one for each supported region.

CALRAM Protection (SP) bit is used to protect the CALRAM on the L-bus from U-bus accesses.
Any attempt to set or clear the SP bit from the U-bus side has no affect.
Once this bit is set, the L2U blocks all CALRAM accesses initiated by the U-bus masters and the
access is terminated with a data error on the U-bus.
If L-bus show cycles are enabled, setting this bit will disable L-bus CALRAM show cycles.
LSHOW bits are used to configure the show cycle mode for cycles accessing the L-bus slave e.g.
CALRAM
00 Disable show cycles
01 Show address and data of all L-bus space write cycles
10 Reserved
11 Show address and data of all L-bus space read and write cycles
Reserved
