14.4.3
The LBC provides an SDRAM interface (machine) for the local bus. The machine provides the control
functions and signals for Intel PC133 and JEDEC-compliant SDRAM devices. Each bank can control an
SDRAM device on the local bus.
14.4.3.1
The memory controller supports any SDRAM configuration with the restrictions that all SDRAM devices
that reside on the bus should have the same port size and timing parameters (as defined in LSDMR).

lines. Note that address signals A[2:0] of the SDRAM connect directly to LA[27:29], address signal A10
connects to the LBCs dedicated LSDA10 signal, while the remaining address bits (except A10) are latched
from LAD[20:26].
