Description

Module Control

Fields

RDYLOWF

DC-DC Converter Ready Low Flag.

0 (NOT_SET): The output voltage (VDC) is below the threshold set in the RDYLOWTH threshold field (RDYLOWTH).

1 (SET): The output voltage (VDC) is above the threshold set in the RDYLOWTH threshold field (RDYLOWTH).

RDYHIGHF

DC-DC Converter Ready High Flag.

0 (NOT_SET): The output voltage (VDC) has not exceeded 105% of the programmed output value.

1 (SET): The output voltage (VDC) has exceeded 105% of the programmed output value.

DROPOUTF

DC-DC Converter Dropout Flag.

0 (NOT_SET): The input voltage (VBATDC) is more than 0.4 V above the output voltage (VDC). The DC-DC converter is not in dropout.

1 (SET): The input voltage (VBATDC) is less than 0.4 V above the output voltage (VDC). The DC-DC converter is in dropout, and firmware should enable the bypass switch (BEN=1).

BGRDYF

Bandgap Ready Flag.

0 (NOT_SET): The bandgap voltage is not above the threshold.

1 (SET): The bandgap voltage is above the threshold.

OSCDIS

Oscillator Disable.

0 (INACTIVE): Enable the DC-DC local oscillator.

1 (ACTIVE): Disable the DC-DC local oscillator.

CLKSEL

Clock Source Select.

0 (DCDCOSC): Select the local DC-DC oscillator as the clock source.

1 (APB): Select the APB clock as the clock source.

CLKDIV

Clock Divider.

0 (DIV1): Use the APB clock divided by 1 as the converter switching frequency.

1 (DIV2): Use the APB clock divided by 2 as the converter switching frequency.

2 (DIV4): Use the APB clock divided by 4 as the converter switching frequency.

3 (DIV8): Use the APB clock divided by 8 as the converter switching frequency.

4 (DIV16): Use the APB clock divided by 16 as the converter switching frequency.

ADCSYNCEN

ADC Synchronization Enable.

0 (DISABLED): Do not synchronize the ADC to the DC-DC converter.

1 (ENABLED): Synchronize the ADC to the DC-DC converter.

CLKINVEN

Clock Inversion Enable.

0 (DISABLED): Do not invert the APB clock input.

1 (ENABLED): Invert the APB clock input.

ADCCLKINVEN

ADC Clock Inversion Enable.

0 (DISABLED): Do not invert the ADC clock derived from the DC-DC switching frequency.

1 (ENABLED): Invert the ADC clock derived from the DC-DC switching frequency.

OUTVSEL

Output Voltage Select.

MIEN

Module Interrupt Enable.

0 (DISABLED): Disable DC-DC module interrupts.

1 (ENABLED): Enable DC-DC module interrupts.

MINPWSEL

Minimum Pulse Width Select.

0 (DISABLED): Disable pulse skipping.

1 (10_NS): Set the minimum pulse width to 10 ns.

2 (20_NS): Set the minimum pulse width to 20 ns.

3 (40_NS): Set the minimum pulse width to 40 ns.

PSMD

Power Switch Mode.

0 (SWSEL0): Mode 0. Set the M1 and M2 power switches to each use one MOSFET only.

1 (SWSEL1): Mode 1. Set the M1 and M2 power switches to each use 2 MOSFETS in parallel.

2 (SWSEL2): Mode 2. Set the M1 and M2 power switches to each use 3 MOSFETS in parallel.

3 (SWSEL3): Mode 3. Set the M1 and M2 power switches to each use 4 MOSFETS in parallel.

ASYNCEN

Asynchronous Mode Enable.

0 (DISABLED): Enable DC-DC synchronous mode.

1 (ENABLED): Enable DC-DC asynchronous mode. This mode is more efficient for very light output loads.

ABEN

Automatic Bypass Enable.

0 (DISABLED): Disable automatic bypass.

1 (ENABLED): Enable automatic bypass.

BEN

Bypass Enable.

0 (DISABLED): Disable the MBYP bypass switch.

1 (ENABLED): Enable the MBYP bypass switch.

DCDCEN

DC-DC Converter Enable.

0 (DISABLED): Disable the DC-DC converter.

1 (ENABLED): Enable the DC-DC converter.
