Manual PAUSE Frame Transmission
PAUSE frames are transmitted by directives from the software. When writing the Timer value to
the manual PAUSE frame set register (MPR), manual PAUSE frame transmission is started. With
this method, PAUSE frame transmission is carried out only once.

PAUSE Frame Reception
The next frame is not transmitted until the time indicated by the Timer value elapses after
receiving a PAUSE frame. However, the transmission of the current frame is continued. A
received PAUSE frame is valid only when the RXF bit in the EtherC mode register (ECMR) is set
to 1.
