MCCINT
MII
Complete Interrupt. The MII Man-
agement Command Complete In-
terrupt is set by the Am79C976
controller when a read or write
operation to the MII Data Port
(BCR34) is complete.

When MCCINT is set to 1, INTA

MCCINTE is set to 1.
Read/Write accessible. MCCINT
is cleared by the host by writing a
1. Writing a 0 has no effect.
MCCINT is cleared by H_RESET
and is not affected by S_RESET
or setting the STOP bit.

MCCINTE
MII
Complete Interrupt Enable. If
MCCINTE is set to 1, the
MCCINT bit will be able to set the
INTR bit when the host reads or
writes to the MII Data Port
(BCR34) only. Internal MII Man-
agement Commands will not gen-
erate an interrupt. For instance,
Auto-Poll state machine generat-
ed MII management frames will
not generate an interrupt upon
completion unless there is a com-
pare error which gets reported
through the MAPINT (CSR7, bit
6) interrupt or the MCCIINTE is
set to 1.

Am79C976 controller whenever
the MIIPD bit (BCR32, bit 14)
transitions from 0 to 1 or vice ver-
sa.
Read/Write accessible. MIIP-
DTINT is cleared by the host by
