Module imxrt_ral::dcdc::REG0

DCDC Register 0

Modules

• ADJ_POSLIMIT_BUCK
  adjust value to poslimit_buck register
• CURRENT_ALERT_RESET
  reset current alert signal
• CUR_SNS_THRSH
  Set the threshold of current detector, if the peak current of the inductor exceeds the threshold, the current detector will assert
• DISABLE_AUTO_CLK_SWITCH
  Disable automatic clock switch from internal osc to xtal clock.
• EN_LP_OVERLOAD_SNS
  enable the overload detection in power save mode, if current is larger than the overloading threshold (typical value is 50 mA), DCDC will switch to the run mode automatically
• LP_HIGH_HYS
  Adjust hysteretic value in low power from 12.5mV to 25mV
• LP_OVERLOAD_FREQ_SEL
  the period of counting the charging times in power save mode 0: eight 32k cycle 1: sixteen 32k cycle
• LP_OVERLOAD_THRSH
  the threshold of the counting number of charging times during the period that lp_overload_freq_sel sets in power save mode
• OVERCUR_TRIG_ADJ
  The threshold of over current detection in run mode and power save mode: run mode power save mode 0x0 1 A 0
• PWD_CMP_BATT_DET
  set to “1” to power down the low voltage detection comparator
• PWD_CMP_OFFSET
  power down output range comparator
• PWD_CUR_SNS_CMP
  The power down signal of the current detector.
• PWD_HIGH_VOLT_DET
  power down overvoltage detection comparator
• PWD_OSC_INT
  Power down internal osc. Only set this bit, when 24 MHz crystal osc is available
• PWD_OVERCUR_DET
  power down overcurrent detection comparator
• PWD_ZCD
  power down the zero cross detection function for discontinuous conductor mode
• SEL_CLK
  select 24 MHz Crystal clock for DCDC, when dcdc_disable_auto_clk_switch is set.
• STS_DC_OK
  Status register to indicate DCDC status. 1’b1: DCDC already settled 1’b0: DCDC is settling
• XTALOK_DISABLE
  1’b1: Disable xtalok detection circuit 1’b0: Enable xtalok detection circuit
• XTAL_24M_OK
  set to 1 to switch internal ring osc to xtal 24M
