management frames. For in-
stance, when MCCIINTE is set to
1 and the Auto-Poll state ma-
chine generates a MII manage-
ment frame, the MCCIINT will set
the INTR bit upon completion of
the MII management frame re-
gardless of the comparison out-
come.
Read/Write accessible always.
MCCIINTE is set to 0 by
H_RESET and is not affected by
S_RESET or setting the STOP
bit.
1
MIIPDTINT MII PHY Detect Transition Inter-
rupt. The MII PHY Detect Transi-
tion Interrupt is set by the
Am79C972 controller whenever
the MIIPD bit (BCR32, bit 14)
transitions from 0 to 1 or vice ver-
sa.
Read/Write accessible always.
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.
0
MIIPDTINTE MII PHY Detect Transition Inter-
rupt Enable. If MIIPDTINTE is set
to 1, the MIIPDTINT bit will be
able to set the INTR bit.
Read/Write accessible always.
MIIPDTINTE is set to 0 by
H_RESET and is not affected by
S_RESET or setting the STOP
bit.
