348 . A description of the SMSC registers is probably in order here,
349 . although for details, the SMC datasheet is invaluable.
350 .
351 . Basically, the chip has 4 banks of registers ( 0 to 3 ), which
352 . are accessed by writing a number into the BANK_SELECT register
353 . ( I also use a SMC_SELECT_BANK macro for this ).
354 .
355 . The banks are configured so that for most purposes, bank 2 is all
356 . that is needed for simple run time tasks.
