+ . A description of the SMSC registers is probably in order here,

+ .
+ . Basically, the chip has 4 banks of registers ( 0 to 3 ), which
+ . are accessed by writing a number into the BANK_SELECT register
+ . ( I also use a SMC_SELECT_BANK macro for this ).
+ .
+ . The banks are configured so that for most purposes, bank 2 is all
+ . that is needed for simple run time tasks.
