Preamble Saving Control
When bit 10 of register 20 is cleared and bit 11 of
register 20 is set, the 10M TX preamble count is reduced.
1: 10-bit preamble bit is reduced.
0: 20-bit preamble bits is reduced.
10M TX Amplitude Control Disabled
1: disable TX amplitude reduce function
0: when cable is unconnected with link partner, the TX amplitude is
reduced for power saving.
TX Power Saving Control Disabled
1: disable TX driving power saving function
0: when cable is unconnected with link partner, the driving current of
transmit is reduced for power saving.
