FULL/HALF DUPLEX SELECT
This pin selects Half/Full Duplex operation mode.
This pin must be externally pulled low (typically x kΩ) in order to configure
the W3150A+ for Full Duplex operation.
Low = Full Duplex
High = Half Duplex
SPI Enable
This pin selects Enable/disable of the SPI Mode.
This pin is internally pulled down for previous W3150A users. Even if there
is no signal connection to this pin, it asserts low internally. Thereby, in case
of change to W3150A+, there is no effort to change previous board design.
Low = SPI Mode Disable
High = SPI Mode Enable
FACTORY TEST INPUT
Used to check the chip's internal functions. This should be tied low (pull-
down) during normal operation.
