DESCRIPTIONS
-
The MAC Receive Pause Count keeps the operand field of the
PAUSE control frame. It indicates how many slot time (512 bit time)
the Tx of EMC will be paused.
MAC Receive Pause Current Count Register (MRPCC)
The EMC of W90P710 supports the PAUSE control frame reception and recognition. If EMC received
a PAUSE control frame, the operand field of the PAUSE control frame will be extracted and stored into
a down count timer. The MRPCC shows the current value of that down count timer for S/W to know
how long the Tx of EMC will be paused. The MRPCC is read only and write to this register has no
effect.
