Function
A1 NC
-
No Connection pin
No internal bonding. This pin should be connected to ground (VSS1, VSS2 or VSS3 pin).
MIC Power Supply Pin
Common Voltage Output Pin, 0.45 x AVDD
Bias voltage of ADC inputs and DAC outputs.
Ground 1 Pin
Analog Power Supply Pin, 2.6 ~ 3.6V
Output Pin for Loop Filter of PLL Circuit (AIN3 bit = “0”: PLL is available.)
This pin should be connected to VSS1 with one resistor and capacitor in series.
Rch Analog Input 3 Pin (AIN3 bit = “1”: PLL is not available.)
No Connection pin
No internal bonding. This pin should be connected to ground (VSS1, VSS2 or VSS3 pin).
I
2
C Control Mode Pin. This pin should be tied to AVDD.
Power-Down Mode Pin (This pin is valid only for the Audio Block)
“H”: Power-up, “L”: Power-down
This pin does not apply to a power down and a reset for the TSC block and TSC related
registers. Power-down on the TSC block is determined by the PD0 bit shown in
Table 61
.
