Should Multiple PWM Outputs Function Concurrently?

[microPaul]

I seem to continue to be PWM challenged.

I'm using a homebrew board with an AVR64DB64. From the documentation on the DxCore GitHub page it looks like TCA0 will provide six PWM outputs. And I do get six PWM outputs on Port D (I change the value of PORTMUX.TCAROUTEA to 0x03). My "problem" is that I only can get one of the PWM outputs to work at a time. If I have multiple AnalogWrite statements, like:

    analogWrite(PIN_PD1, 32);
    analogWrite(PIN_PD2, 128);
    analogWrite(PIN_PD3, 190);  
    analogWrite(PIN_PD4, 45);     
    analogWrite(PIN_PD5, 99); 

then only the last statement is effective. Is this the way PWM is supposed to work? Only one TCA0 PWM output active at a time? I thought (or was hoping) that I could get six concurrently operating PWM outputs from one TCA timer. Please let me know if the one-at-a-time PWM output that I'm seeing is the intended functionality. I'm using the 1.5.11 version of the DxCore.

Thanks!

Here's the whole program that I'm using for test purposes:

#undef Serial
#define Serial Serial4  // Using UART4 No Alt (PE0, PE1)
                                   
void setup() {

    //Serial.swap(0); // no need to swap for this UART pin assignment
    Serial.begin(57600, SERIAL_8N1); 
    Serial.println("");   
    Serial.println("_test_pwm_TCA_DB64_241207-01"); 
    Serial.println("");  
    delay(500); // give serial port time to send data


    PORTA.OUTCLR = PIN7_bm;  // PA7 - LED off
    PORTA.DIRSET = PIN7_bm;  // LED DDR set for output
    
    // now set up things for PWM output.  Trying to get six concurrent PWM outputs from TCA0 on Port D
    Serial.printf("PORTMUX.TCAROUTEA = 0x%02x\n", PORTMUX.TCAROUTEA);
    PORTMUX.TCAROUTEA = 0x03; // select D output
    
    analogWrite(PIN_PD0, 64);
    analogWrite(PIN_PD1, 32);
    analogWrite(PIN_PD2, 128);
    analogWrite(PIN_PD3, 190);  
    analogWrite(PIN_PD4, 45);     
    analogWrite(PIN_PD5, 99);      
    Serial.printf("PORTMUX.TCAROUTEA = 0x%02x\n", PORTMUX.TCAROUTEA);
}

I am greatly concerned upon reading this, it is a high priority for investigation.
