问题一：RX_MODE_WTO是什么模式？

问题二：

Channel/Channel Number/Frequency(MHz)/lo1_idiv[7:0]Fractional/lo1_num[15:01]  

 1         11            2405            149 / 0x95           20480 / 0x5000

上面自己对应关系怎么确定的？

问题三：

 rtx_mode = RESET_DELAY;
 
 /* Add a delay to debouce the reset switch on development boards ~200ms */
 TPM1SC = 0x0D; /* Set the Timer module to use BUSCLK as reference with Prescalar at / 32 */
 
 do
 {
  timer_hi = TPM1CNTH; /* Get the value of the timer register (hi byte) */
  timer_lo = TPM1CNTL; /* Get the value of the timer register (lo byte) */
 }
 while (timer_lo <= 0x80); /* Poll for TIMER LO to be greater than 0x80 at 4MHz/32*/
 
 TPM1SC = 0x00; /* Return to reset values */

 rtx_mode = SYSTEM_RESET_MODE;
 init_gpio();
 SPI1C1 = 0x50; /* Init SPI */
 SPI1C2 = 0x00;
 SPI1BR = 0x00;
 IRQSC = 0x14; /* Turn on the IRQ pin. */
 rtx_mode = MC13192_RESET_MODE;
 MC13192_RESET = 1; /* Take MC13192 out of reset */
 

这段程序中rtx_mode为什么多次出现？
