range for the second VSB to local
bus map decoder. Only the
upper 16 bits of this field are
significant (or used). Default =
00000000.
VSBC2 Slave Ending Address #2 00000000 Ending address of an address
range for the second VSB to local
bus map decoder. Only the
upper 16 bits of this field are
significant (or used). Default =
00000000.
