Preamble Saving Control
when both bit 10 and 11 of register 14H are set, the 10BASE-T
transmit preamble count is reduced.
1: 12-bit preamble is reduced.
0: 22-bit preamble is reduced.
Transmit Amplitude Control Disabled
1: when cable is unconnected with link partner, the TX amplitude is
reduced for power saving.
0: disable Transmit amplitude reduce function
Transmit Power Saving Control Disabled
1: when cable is unconnected with link partner, the driving current
of transmit is reduced for power saving.
0: disable transmit driving power saving function
