void SetupAfterColdResetWakeupFromShutDownCfg1

(

uint32_t

ccfg_ModeConfReg

)

First part of configuration required after cold reset and when waking up from shutdown.

Configures the following based on settings in CCFG (Customer Configuration area:

• Boost mode for CC13xx devices
• Minimal VDDR voltage threshold used during sleep mode
• DCDC functionality:
  • Selects if DCDC or GLDO regulator will be used for VDDR in active mode
  • Selects if DCDC or GLDO regulator will be used for VDDR in sleep mode

In addition the battery monitor low limit for internal regulator mode is set to a hard coded value.

Parameters

ccfg_ModeConfReg

is the value of the CCFG_O_MODE_CONF_1 register

Returns

None
