`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_RELOAD = $0002;`	When set it will read the EEPROM and update relevant registers with its contents
