CC2640 ADC如何配置auxIo？

最近使用CC2640的ADC，但发现OneShotADC（）函数的输入变量不知如何配置。它说参考MUX3寄存器，但是TRM中找不到MUX3的配置信息。挺急的，希望大神能够帮我解决问题。程序我贴上来。麻烦大神了。谢谢。

// auxIo, see MUX3 Register (Offset = 3h) [reset = X]
// auxIo, sensor controller engine IO, will map to M3's IO automatilcally
// for DIO23, auxIO7, the value should be 80h, 0x80
uint16_t OneShotADC(uint8_t auxIo)
{
static __root uint16_t retval = 0xABBA;
uint32_t turnedOnClocks = 0;

AUXADCSelectInput(ADC_COMPB_IN_AUXIO7);

// Only turn on clocks that are not already enabled. Not thread-safe, obviously.
turnedOnClocks |= AUXWUCClockStatus(AUX_WUC_ADC_CLOCK)?0:AUX_WUC_ADC_CLOCK;
turnedOnClocks |= AUXWUCClockStatus(AUX_WUC_ADI_CLOCK)?0:AUX_WUC_ADI_CLOCK;
turnedOnClocks |= AUXWUCClockStatus(AUX_WUC_SOC_CLOCK)?0:AUX_WUC_SOC_CLOCK;

// Enable clocks and wait for ready
AUXWUCClockEnable(turnedOnClocks);
while(false == AUXWUCClockStatus(turnedOnClocks));

// Set ADC Config: Sample mode Synchronous, 3 cycles sample, Reset, Disable.
HWREGB(AUX_ADI4_BASE + ADI_4_AUX_O_ADC0) = (0 << ADI_4_AUX_ADC0_SMPL_MODE_S) |

(0 << ADI_4_AUX_ADC0_RESET_N_S) |

// Set reference source: Keep powered when idle, Fixed Src 4.3V, Enable reference system

// Connect the muxed AUX IO Channel, light sensor is DIO23, which is AUXIO7 on the 7x7 package
//HWREGB(AUX_ADI4_BASE + ADI_4_AUX_O_MUX3) = auxIo;
HWREGB(AUX_ADI4_BASE + 0x00000003) = auxIo;

// Release ADC from reset and enable
HWREGB(AUX_ADI4_BASE + ADI_4_AUX_O_ADC0) |= (1 << ADI_4_AUX_ADC0_RESET_N_S) |
(1 << ADI_4_AUX_ADC0_EN_S );

// Control M3's Analog Interface. Set polarity for trigger, but we don't care. Set trig source to NO_EVENT. Enable ADC interface for the remaining register writes.
HWREG(AUX_ANAIF_BASE + AUX_ANAIF_O_ADCCTL) = (0 << AUX_ANAIF_ADCCTL_START_POL_S) |
(9 << AUX_ANAIF_ADCCTL_START_SRC_S ) | // 9 is NO_EVENT, which is what we want for software trigger
(1 << AUX_ANAIF_ADCCTL_CMD_S); //

// Trigger the ADC conversion
HWREG(AUX_ANAIF_BASE + AUX_ANAIF_O_ADCTRIG) = (1 << AUX_ANAIF_ADCTRIG_START_S);

// Wait until it's finished (when fifo is not empty)
while ( 1 == (HWREG(AUX_ANAIF_BASE + AUX_ANAIF_O_ADCFIFOSTAT) & AUX_ANAIF_ADCFIFOSTAT_EMPTY) );

// Read out value from FIFO
retval = HWREG(AUX_ANAIF_BASE + AUX_ANAIF_O_ADCFIFO);


// Clean up.
// Disable reference system
HWREGB(AUX_ADI4_BASE + ADI_4_AUX_O_ADCREF0) &= ~(1 << ADI_4_AUX_ADCREF0_EN_S );

// Turn off clocks
AUXWUCClockDisable(turnedOnClocks);
// Turn off ADC module
HWREGB(AUX_ADI4_BASE + ADI_4_AUX_O_ADC0) = (0 << ADI_4_AUX_ADC0_RESET_N_S) |
(0 << ADI_4_AUX_ADC0_EN_S );

return retval;
}
