Tool/software: Code Composer Studio
Hello,
I've been reading up on the brown-out detection level in the technical reference manual. I think there is an inconsistency between the CCFG startup file as distributed with the Simplelink SDK.
The technical reference manual describes for MODE_CONF register the VDDS BOD Level configuration bit (page 715 rev. H):
* '0' means 2.0V which is necessary for maximum PA output power
* '1' means 1.8V (or 1.7V for external regulator mode), which is default
However, the implementation of ccfg.c delivered with the simplelink SDK is the following:
#if ( CCFG_FORCE_VDDR_HH )
#define SET_CCFG_MODE_CONF_VDDS_BOD_LEVEL 0x1 // Special setting to enable forced VDDR HH voltage
#else
#ifndef SET_CCFG_MODE_CONF_VDDS_BOD_LEVEL
// #define SET_CCFG_MODE_CONF_VDDS_BOD_LEVEL 0x0 // VDDS BOD level is 2.0V
#define SET_CCFG_MODE_CONF_VDDS_BOD_LEVEL 0x1 // VDDS BOD level is 1.8V (or 1.65V for external regulator mode)
#endif
#endif
When I enable CCFG_FORCE_VDDR_HH (set as '1'), maximum PA output power is enabled (I assume). According to the reference manual, I would expect the bit is set to '0'.
Why does the above statement perform the opposite of what is described in the reference manual (set to '1')?
Kind Regards
Linda
