Check 6: SDRAM I/F OK?
<Outline> The capacity of the communication I/F SDRAM between LSI and the memory should be
64 Mbit to assure the MPEG stream data as a buffer.

Note that XCSM, XWE, XCAS, XRAS and XCSM in IC1480 are called in a different manner
in IC1501 as NCSM, NWE, NCAS, NRAS and NCSM respectively.

<Check>
Check conduction between "Spot to check 1" and "Spot to check 2" when the power is OFF.
If NG is found, check soldering and defective components in all processes for "output -> input"
at the relevant spots.
