Manual Mode allows software to directly control the serial clock output (MDCLK_O), the serial data output enable (MDIO_OE_N), and the serial data output (MDIO_O). The serial data input can also be read (MDIO_I). This mode is enabled when the [31] MANUALMODE bit is set in the MDIO MDIO_POLL_REG register. Manual Mode is intended to be used by software for slow speed general purpose IO operations and not for MDIO PHY operations.
