CHAPTER 2 PIN FUNCTIONS
72
2.2.14 Dedicated VDD and GND Signals
Table 2-14. Dedicated VDD and GND Signals
Signal
Description of function
VDDP
This is the dedicated VDD for the PLL.
GNDP
This is the dedicated GND for the PLL.
CVDD
This is the dedicated VDD for the internal oscillator.
CGND
This is the dedicated GND for the internal oscillator.
DVDD
This is the dedicated VDD for the D/A converter. The voltage applied to this pin becomes the maximum
value for AUDIOOUT’s analog output.
DGND
This is the dedicated GND for the D/A converter. The voltage applied to this pin becomes the minimum
value for AUDIOOUT’s analog output.
AVDD
This is the dedicated VDD for the A/D converter. The voltage applied to this pin becomes the maximum
voltage value for the A/D interface signals.
AGND
This is the dedicated GND for the A/D converter. The voltage applied to this pin becomes the minimum
voltage value detectable by the A/D interface signals.
PIUVDD
This is the dedicated VDD for the touch panel interface.
PIUGND
This is the dedicated GND for the touch panel interface.
