This register can be read and written as a word
or as two individual bytes.
The Interrupt Mask Register bits enable the
appropriate bits when high and disable them
when low. An enabled bit being set will cause a
hardware interrupt.
EPH INT - Set when the Ethernet Protocol
Handler section indicates one out of various
possible special conditions. This bit merges
exception type of interrupt sources, whose
service time is not critical to the execution speed
of the low level drivers. The exact nature of the
interrupt can be obtained from the EPH
