13.1
The Li bus state controller (LBSC) functions enable LCD controller and Open HCI compliant
USB Host controller to link directly with synchronous DRAM. LBSC is a slave bus state
controller of BSC.
13.1.1
The LBSC has the following features:
• Direct interface to synchronous DRAM
13.1.2
The LBSC does not have any register inside, but refers BSC registers shown in table 13.1.
