RESET
This pin is active Low input to initialize or re-initialize W3150A+.
Asserting this pin low for at least 2us will force a reset process to occur
which will result in all internal registers re-initializing to their default
states.
CLOCK
This pin is the Primary clock required for internal operation of W3150A+.
25MHz is required. In general, PHY driving clock can be shared for saving
cost.
Note) Sharing crystal source clock with multiple devices may cause some
troubles. In our reference design, we used one crystal for both PHY and
W3150A+ with verification.
But for other kind of PHY, please confirm safety prior to decision.
ADDRESS PIN or SCLK (Serial Clock)
This pin is used to select a register or memory.
When asserting SPI_EN pin high, this pin is used to SPI Clock signal Pin.
ADDRESS PIN or /SS (Slave Select) *
This pin is used to select a register or memory.
When asserting SPI_EN pin high, this pin is used to SPI Slave Select signal
Pin. In only SPI Mode, this pin is active low
ADDRESS PIN or MOSI (Master Out Slave In) *
This pin is used to select a register or memory.
When asserting SPI_EN pin high, this pin is used to SPI MOSI signal pin.
ADDRESS PIN or MISO (Master In Slave Out) *
This pin is used to select a register or memory.
When asserting SPI_EN pin high, this pin is used to SPI MISO signal pin.
ADDRESS PINS
These pins are used to select a register or memory.
DATA PINS
These pins are used to read and write register or memory data.
