Use PE, how to set the MUX of uart port to 3

We use

      1. MKL02Z32;

      2. Kinetis Design Studio V: 3.2.0;

      3. PE

 

In PE, We use the component AsynchroSerial for UART0.

 

In Component Inspector.

      1. set "ADC0_SE4/PTB2/IRQ_7/UART0_RX/UART0_TX" for RX of the UART0.

      2. Set "ADC0_SE5/CMP0_IN3/PTB1/IRQ_6/UART0_TX/UART0_RX" for the TX of the UART0.

 

After Click "Generate Processor Expert Code", the tool will generate code auto.

 

But the uart can no work .

 

In function ASerialLdd1_Init(),

 

  PORTB_PCR2 = (uint32_t)((PORTB_PCR2 & (uint32_t)~(uint32_t)(
                PORT_PCR_ISF_MASK |
                PORT_PCR_MUX(0x05)
               )) | (uint32_t)(
                PORT_PCR_MUX(0x02)
               ));
  /* PORTB_PCR1: ISF=0,MUX=2 */
  PORTB_PCR1 = (uint32_t)((PORTB_PCR1 & (uint32_t)~(uint32_t)(
                PORT_PCR_ISF_MASK |
                PORT_PCR_MUX(0x05)
               )) | (uint32_t)(
                PORT_PCR_MUX(0x02)
               ));

 

When i change the PORT_PCR_MUX(0x02) to PORT_PCR_MUX(0x03), then the UART can work fine.

 

 

Use PE, how to set the MUX of uart port to 3???

 

Thanks.
