purposes only
Reserved.
Powers down the device after the DC-DC converter completes startup if a VDDIO brownout occurs. This
function is only active when 5V is not present. Additionally, software should clear this bit and disable this
function after the system is configured for a VDDIO brownout and the VDDIO brownout interrupt is enabled.
Disables the default behavior of the voltage stepping algorithm when the TRG field is updated. By default,
the control loop steps sequentially through 25mV steps on both target and brownout voltage to minimize
transients during TRG adjustments.
When this bit is set, the entire target voltage and brownout adjustment takes place at one time, which will
speed transitions, but will result in increased supply transients as well as possible brownouts when the new
(TRG - BO_OFFSET) >= old TRG.Thus, it is recommended to change TRG by less than the (BO_OFFSET-2)
value when using DISABLE_STEPPING. This bit should be set high when powering VDDIO from the
integrated linear regulators.
Disable the VDDIO switching converter output. The switching converter is enabled by default when the
battery is present or the ENABLE_DCDC is set.
Reserved.
Number of 25mV steps between linear regulator output voltage and switching converter target.
