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

. although for details, the SMC datasheet is invaluable.
|

.
|
|
. 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.
