MIIPDTINTE PHY Detect Transition Interrupt
MCCIINTE PHY Management Command
MIIPDTINT PHY Detect Transition Interrupt.

RES
affected by S_RESET or setting
the STOP bit.
Complete Internal Interrupt En-
able. If MCCIINTE is set to 1, the
MCCIINT bit will be able to set
the INTR bit when the internal
state machines generate man-
agement frames. For instance,
when MCCIINTE is set to 1 and
the Auto-Poll state machine gen-
erates a management frame, the
MCCIINT will set the INTR bit
upon completion of the manage-
ment frame regardless of the
comparison outcome.
This bit is always read/write ac-
cessible. MCCIINTE is set to 0 by
H_RESET and is not affected by
S_RESET or setting the STOP
bit.
The PHY Detect Transition Inter-
rupt is set by the Am79C978 con-
troller whenever the MIIPD bit
(BCR32, bit 14) transitions from 0
to 1 or vice versa.
This bit is always read/write ac-
cessible. MIIPDTINT is cleared
by the host by writing a 1. Writing
a 0 has no effect. MIIPDTINT is
cleared by H_RESET and is not
affected by S_RESET or setting
the STOP bit.
Enable. If MIIPDTINTE is set to 1,
the MIIPDTINT bit will be able to
set the INTR bit.
This bit is always read/write ac-
cessible. MIIPDTINTE is set to 0
by H_RESET and is not affected
by S_RESET or setting the STOP
bit.
