Description

DCDC Register 0

Fields

PWD_ZCD

Power Down Zero Cross Detection

0 (powered_up): Zero cross detetion function powered up

1 (powered_down): Zero cross detetion function powered down

DISABLE_AUTO_CLK_SWITCH

Disable Auto Clock Switch

0 (xtal_clk): If DISABLE_AUTO_CLK_SWITCH is set to 0 and 24M xtal is OK, the clock source will switch from internal ring OSC to 24M xtal automatically

1 (sel_clk): If DISABLE_AUTO_CLK_SWITCH is set to 1, SEL_CLK will determine which clock source the DCDC uses

SEL_CLK

Select Clock

0 (int_rng_osc): DCDC uses internal ring oscillator

1 (xtal_24M): DCDC uses 24M xtal

PWD_OSC_INT

Power down internal osc

0 (powered_up): Internal oscillator powered up

1 (powered_down): Internal oscillator powered down

PWD_CUR_SNS_CMP

Power down signal of the current detector.

0 (powered_up): Current Detector powered up

1 (powered_down): Current Detector powered down

CUR_SNS_THRSH

Current Sense (detector) Threshold

0 (select_zero): 150 mA

1 (select_one): 250 mA

2 (select_two): 350 mA

3 (select_three): 450 mA

4 (select_four): 550 mA

5 (select_five): 650 mA

PWD_OVERCUR_DET

Power down overcurrent detection comparator

0 (enabled): Overcurrent detection comparator is enabled

1 (disabled): Overcurrent detection comparator is disabled

OVERCUR_TRIG_ADJ

Overcurrent Trigger Adjust

0 (select_zero): In Run Mode, 1 A. In Power Save Mode, 0.25 A

1 (select_one): In Run Mode, 2 A. In Power Save Mode, 0.25 A

2 (select_two): In Run Mode, 1 A. In Power Save Mode, 0.2 A

0 (enabled): Enable xtalok detection circuit

1 (disabled): Disable xtalok detection circuit and always outputs OK signal “1”

CURRENT_ALERT_RESET

Reset Current Alert Signal

0 (not_reset): Current Alert Signal not reset

1 (reset): Current Alert Signal reset

XTAL_24M_OK

24M XTAL OK

0 (int_rng_osc): DCDC uses internal ring OSC
