| * A description of the SMC 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. |
