`SMC91X_CONFIG_NO_WAIT = $1000;`	When set, does not request additional wait states. An exception to this are accesses to the Data Register if not ready for a transfer.
`SMC91X_CONFIG_EPH_POWER_EN = $8000;`	Used to selectively power transition the EPH to a low power mode. When this bit is cleared (0), the Host will place the EPH into a low power mode.

`SMC91X_CTL_EEPROM_SELECT = $0004;`	This bit allows the CPU to specify which registers the EEPROM RELOAD or STORE refers to
`SMC91X_CTL_RELOAD = $0002;`	When set it will read the EEPROM and update relevant registers with its contents

`SMC91X_MMU_CMD_RESET = (2 shl 5);`	RESET MMU TO INITIAL STATE (Frees all memory allocations, clears relevant interrupts, resets packet FIFO pointers)
`SMC91X_MMU_CMD_REMOVE = (3 shl 5);`	REMOVE FRAME FROM TOP OF RX FIFO (To be issued after CPU has completed processing of present receive frame)
`SMC91X_MMU_CMD_RELEASE = (4 shl 5);`	REMOVE AND RELEASE TOP OF RX FIFO (Like 3) but also releases all memory used by the packet presently at the RX FIFO output)
`SMC91X_MMU_CMD_FREEPKT = (5 shl 5);`	RELEASE SPECIFIC PACKET (Frees all pages allocated to the packet specified in the PACKET NUMBER REGISTER)
`SMC91X_MMU_CMD_ENQUEUE = (6 shl 5);`	ENQUEUE PACKET NUMBER INTO TX FIFO (This is the normal method of transmitting a packet just loaded into RAM)
`SMC91X_MMU_CMD_RSTTXFIFO = (7 shl 5);`	RESET TX FIFOs (This command will reset both TX FIFOs)

`SMC91X_PTR_RCV = $8000;`	When RCV is set the address refers to the receive area and uses the output of RX FIFO as the packet number, when RCV is clear the address refers to the transmit area and uses the packet number at the Packet Number Register.
`SMC91X_PTR_AUTOINC = $4000;`	It will auto-increment on accesses to the data register when AUTO INCR is set. The increment is by one for every byte access, by two for every word access, and by four for every double word access.
