Signal descriptions
2.12
VCC Supply Voltage
The VCC Supply Voltage is the core supply voltage.
2.13
VCCQ Supply Voltage
VCCQ provides the power supply for the I/O pins. This allows all Outputs to be powered
independently from the core power supply, VCC.
2.14
VSS Ground.
The VSS Ground is the reference for all voltage measurements.
2.15
VSSQ Ground
VSSQ ground is the reference for the input/output circuitry driven by VCCQ. VSSQ must be
connected to VSS.
