Enable 100ohm load on the regulated 4.2V output. This bit should not be set unless recommended by
Freescale.
Reserved.
Enable fault detection in the battery charger. When enabled, this bit will power down the battery charger
when the VDD5V voltage falls below the battery voltage. The fault can be cleared by cycling
PWD_CHARGE_4P2. The fault detection is visible through HW_POWER_STS_VDD5V_FAULT.
Setting this bit disables the CHRGSTS status bit. Disabling CHRGSTS should only be done when the
switching converter is enabled during battery charge if noise from the switching converter causes CHRGSTS
to toggle excessively.
This bit has no effect.
Reserved.
Power-down the battery charge circuitry. This should only be set low when 5V is present. This bit can be
set (charger turned off) automatically by the threshold units of the LRADC if programmed to do so.
