4x Independent PWM - Code Check Required

[snoopy20]

Hi,

I had this working, I'm sure of it. Now though I get 100% duty on one channel and 0% on another. Something's not right.

  volatile uint16_t nrf_pwm_duty[4] = {CFG_PWM_INVERT};
  
  NRF_PWM0->COUNTERTOP  = CFG_PWM_COUNT; // 200 = 16MHz/200 = 80KHz, 10mA per step 
  NRF_PWM0->DECODER     = (PWM_DECODER_LOAD_Individual << PWM_DECODER_LOAD_Pos) | (PWM_DECODER_MODE_RefreshCount << PWM_DECODER_MODE_Pos);
  NRF_PWM0->SEQ[0].PTR  = (uint32_t) &nrf_pwm_duty << PWM_SEQ_PTR_PTR_Pos;
  NRF_PWM0->SEQ[0].CNT  = (sizeof(nrf_pwm_duty) / sizeof(uint16_t)) << PWM_SEQ_CNT_CNT_Pos;
  NRF_PWM0->SHORTS      = PWM_SHORTS_LOOPSDONE_SEQSTART0_Enabled << PWM_SHORTS_LOOPSDONE_SEQSTART0_Pos;
  NRF_PWM0->PSEL.OUT[CFG_PWM_OUTPUT_USB_NUM] = (CFG_PIN_PWM_USB_NUM << PWM_PSEL_OUT_PIN_Pos) | (PWM_PSEL_OUT_CONNECT_Connected << PWM_PSEL_OUT_CONNECT_Pos);
  NRF_PWM0->PSEL.OUT[CFG_PWM_OUTPUT_FRONT_NUM] = (CFG_PIN_PWM_FRONT_NUM << PWM_PSEL_OUT_PIN_Pos) | (PWM_PSEL_OUT_CONNECT_Connected << PWM_PSEL_OUT_CONNECT_Pos);
  NRF_PWM0->PSEL.OUT[CFG_PWM_OUTPUT_REAR_NUM] = (CFG_PIN_PWM_REAR_NUM << PWM_PSEL_OUT_PIN_Pos) | (PWM_PSEL_OUT_CONNECT_Connected << PWM_PSEL_OUT_CONNECT_Pos);
  NRF_PWM0->PSEL.OUT[CFG_PWM_MPPT_NUM] = (CFG_PIN_PWM_MPPT_NUM << PWM_PSEL_OUT_PIN_Pos) | (PWM_PSEL_OUT_CONNECT_Connected << PWM_PSEL_OUT_CONNECT_Pos);
  
  NRF_PWM0->ENABLE = PWM_ENABLE_ENABLE_Enabled << PWM_ENABLE_ENABLE_Pos;
  NRF_PWM0->TASKS_SEQSTART[0] = 1;

Pins are correct, my focus is CFG_PWM_OUTPUT_FRONT_NUM which is number/channel 1 in the duty array.

I set the value with a duty of 5,  nrf_pwm_duty[outputChannel] = CFG_PWM_INVERT | value;  // (0x8005)

The pin is at 100%. If I disable PWM it's at floating voltage (correct).
