Bit [0]:
Reset GIGA port 0
0: Normal operation (default)
1: Reset Gigabit port 0. Normally used when a new Phy is connected (Hot swap).
Bit [1]:
GIGA port 0 use MII interface (10/100M)
0: Gigabit port operations at 1000 mode (default)
1: Gigabit port operations at 10/100 mode
Bit [2]:
Device information insertion enable for Gigabit port 0
0: Disable preamble stack device ID insertion (default).
1: Insert stack device ID into the preamble (must be enabled for ring mode).
Bit [3]:
GIGA port 0 direct flow control (MAC to MAC connection). The ZL50418 supports
direct flow control mechanism; the flow control frame is therefore not sent through
the Gigabit port data path.
0: Direct flow control disabled (default)
1: Direct flow control enabled
Bit [4]:
Reset GIGA port 1
0: Normal operation (default)
1: Reset Gigabit port 1
Bit [5]:
GIGA port 1 use MII interface (10/100M)
0: Gigabit port operates at 1000 mode (default)
1: Gigabit port operates at 10/100 mode
Bit [6]:
Device information attach enable for Gigabit port 1
0: Disable preamble stack device ID insertion (default)
1: Insert stack device ID into the preamble (must be enabled for ring mode).
Bit [7]:
GIGA port 1 direct flow control (MAC to MAC connection). ZL50418 supports direct
flow control mechanism; the flow control frame is therefore not sent through the
Gigabit port data path.
0: Direct flow control disabled (default)
1: Direct flow control enabled
