the DUT board must leave this pin open. Maximum capacitor loading
for this node is not to exceed 50uF.
VDDIO
Interface Supply always provided by the DUT board. Both the DUT
board and the SPIO-4 board power their I/O drivers with this supply
(except the I2C bus – which is always +3.3V). Only the SPI_A related
signals on the GPSI-16 subset are affected by this I/O supply. Voltage
Range: 1.6V to 5.5V. Capable of supplying 100mA.
SCS2_A~
SerialBus A – Chip Select for device 2.
DUT_PWR_Enable
For those DUT boards that support intelligent power-up control, this
signal from the SPIO-4 enables the DUT power regulators.

If a second SPI bus is implemented, then use this pin as shown:
SCS0_B~
SerialBus B – Chip Select for device 0.
Available for implementation specific use. Refer to the DUT
board manual.
If a second SPI bus is implemented, then use this pin as shown:
SDRDY_B~
In certain SPI applications, if required, this pin serves as the DRDY~
signal from the DUT to the SPIO-4.
Available for implementation specific use. Refer to the DUT
board manual.
If a second SPI bus is implemented, then use this pin as shown:
SCK_B
Serial Bus B – Serial Clock from the master to the device.
Available for implementation specific use. Refer to the DUT
board manual.
If a second SPI bus is implemented, then use this pin as shown:
SCS1_B~
SerialBus B – Chip Select for device 1.
Available for implementation specific use. Refer to the DUT
board manual.
If a second SPI bus is implemented, then use this pin as shown:
SMISO_B
