Register Description
Register Functions/Settings
Bit 9, PHY Control Register 2, manually sets the MDI/MDI-X configuration if automatic MDIX is disabled, as indicated
below.
Table 36. MDI/MDI-X Configuration
The mapping of the transmitter and receiver to pins for MDI and MDI-X configuration for 10Base-T, 100Base-TX, and
1000Base-T is shown below. Note that even in manual MDI/MDI-X configuration, the PHY automatically detects and cor-
rects for C and D pair swaps.
