 . A description of the SMSC registers is probably in order here,
60
 . although for details, the SMC datasheet is invaluable.
61
 .
62
 . Basically, the chip has 4 banks of registers ( 0 to 3 ), which
63
 . are accessed by writing a number into the BANK_SELECT register
64
 . ( I also use a SMC_SELECT_BANK macro for this ).
65
 .
66
 . The banks are configured so that for most purposes, bank 2 is all
67
 . that is needed for simple run time tasks.
