    XMC 4700 PORT 15 Output Problems

    Hello I have got a Problem,

    I will declare Ports as Output.

    For example Port 5 works but on Port 15 it doesn’t work. I think I forgot a Register. Can somebody help me?

    #define SETUPPAGE_2 (11UL)

    volatile uint32_t *_Port_IOCR;
    volatile uint32_t *_Port_OMR;

    #define OUTPUT_PUSHPULL (0x10UL)
    #define _Bit (9)

    int main (void)



    _Port_OMR = &(PORT5->OMR);
    _Port_IOCR = &(PORT5->IOCR8);

    *_Port_IOCR &= ~(0x1FUL << SETUPPAGE_2);
    *_Port_IOCR |= ((OUTPUT_PUSHPULL & 0x1FUL) << SETUPPAGE_2);

    void timing_delay(void);

    while (1)

    *_Port_OMR |= (1<<_Bit);

    } // while schleife

    } //main schleife

    Ports 14 and 15 can be used only for analog and digital input, no output. I guess it is because they are shared with the ADC.
    Unfortunately the pin placement tool tries as hard as it can to hide information from you.
