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. -----------------------------------------------------------------------*/ /* . Bank Select Register: . . yyyy yyyy 0000 00xx . xx = bank number . yyyy yyyy = 0x33, for identification purposes. */ #define BANK_SELECT 14 /* Transmit Control Register */ /* BANK 0 */ #define TCR_REG 0x0000 /* transmit control register */ #define TCR_ENABLE 0x0001 /* When 1 we can transmit */ #define TCR_LOOP 0x0002 /* Controls output pin LBK */ #define TCR_FORCOL 0x0004 /* When 1 will force a collision */ #define TCR_PAD_EN 0x0080 /* When 1 will pad tx frames < 64 bytes w/0 */ #define TCR_NOCRC 0x0100 /* When 1 will not append CRC to tx frames */
