DCDC Register 0

Modules§

  • adjust value to poslimit_buck register
  • reset current alert signal
  • Set the threshold of current detector, if the peak current of the inductor exceeds the threshold, the current detector will assert
  • Disable automatic clock switch from internal osc to xtal clock.
  • 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
  • Adjust hysteretic value in low power from 12.5mV to 25mV
  • the period of counting the charging times in power save mode 0: eight 32k cycle 1: sixteen 32k cycle
  • the threshold of the counting number of charging times during the period that lp_overload_freq_sel sets in power save mode
  • The threshold of over current detection in run mode and power save mode: run mode power save mode 0x0 1 A 0
  • set to “1” to power down the low voltage detection comparator
  • power down output range comparator
  • The power down signal of the current detector.
  • power down overvoltage detection comparator
  • Power down internal osc. Only set this bit, when 24 MHz crystal osc is available
  • power down overcurrent detection comparator
  • power down the zero cross detection function for discontinuous conductor mode
  • select 24 MHz Crystal clock for DCDC, when dcdc_disable_auto_clk_switch is set.
  • Status register to indicate DCDC status. 1’b1: DCDC already settled 1’b0: DCDC is settling
  • 1’b1: Disable xtalok detection circuit 1’b0: Enable xtalok detection circuit
  • set to 1 to switch internal ring osc to xtal 24M
