• [DRV_SRC] SysCtrl: SysCtrlSetRechargeBeforePowerDown() now uses C basic type arguments instead of enumerated types. Defines for valid arguments are added and documented.
• [DRV_SRC] SysCtrl: SysCtrlSetRechargeBeforePowerDown() is updated to configure recharge configuration slightly different, reducing maximum recharge period.
• [DRV_SRC] AUX_ADC: External ADC reference is not supported thus removed from AUX_ADC API.
• [DRV_SRC] AUX_ADC: AUXADCReenableInputScaling() is removed from AUX_ADC API and safe usage of AUXADCDisableInputScaling() documented.

Release date: February 25, 2015

Bug fixes & New features

• cc26xxware_2_20_06_14829 is the initial revision and contains as such no bug fixes or new features.

Known Issues

• [DRV_SRC] - STANDBY current consumption when using external regulator mode
  The driverlib function used to setup the recharge rate before entering the STANDBY power mode does not turn off the adaptive rate calculation when in external regulator mode and ends up with minimum recharge rate and a current consumption of approximately 100 micro amps (while expecting approximately 1 micro amps).
