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.
