23.3.23 Manual PAUSE Frame Register (MPR)
MPR is used to set the TIME parameter value of a manual PAUSE frame. When a manual PAUSE
frame is transmitted, the value set in this register is used as the TIME parameter of the PAUSE
frame.

These bits set the TIME parameter value of a manual
PAUSE frame. One bit is equivalent to 512 bit-time.

Note:
The bit-time becomes as follows according to
the transfer speed.
1000 Mbps: 1 bit-time = 1 ns
100 Mbps: 1 bit-time = 10 ns
10 Mbps: 1 bit-time = 100 ns
