This pin is configured using the GPIO3_SELECT and
GPIO3_IO_SELECT bits in the GPIO_CONTROL_REG_1 register.
Digital Input
Reset pin. If set LOW, all blocks set to default conditions and
inputs/outputs set to high impedance. If HIGH, normal operation of
the device resumes. By default, internally pulled HIGH.
Power
Most positive power supply connection for the DDO1/DDO1 output
driver. Connect to any voltage between 1.2V and 2.5V.
Power
Most negative power supply connections for the output drivers.
Connect to ground.
Output
Differential serial data output 1.
Output
Differential serial data output 0.
Power
Most positive power supply connection for the DDO0/DDO0 output
driver. Connect to any voltage between 1.2V and 2.5V.
Power
Decoupling
Connect through decoupling capacitor to ground.
Power
Connect to 1.8V.
Power
Connect to ground.
Input
Connect to high-speed differential clock (AC coupled internally).
Leave unconnected if not using external DFT clock input feature.
Power
