Function Documentation

§ PowerCC26X2_enableHposcRtcCompensation()

void PowerCC26X2_enableHposcRtcCompensation ( void )

Enable RTC compensation when SCLK_LF is derived from HPOSC.

Enables automatic compensation for temperature based clock drift of the RTC when SCLK_LF is derived from HPOSC.

It only needs to be called once after the system boots.

This function should only be called when SCLK_LF is configured to be drived from HPOSC.

§ PowerCC26X2_getResetReason()

PowerCC26X2_ResetReason PowerCC26X2_getResetReason ( void )

Returns the reason for the most recent reset.

Precondition: Power_init()

Postcondition: PowerCC26X2_releaseLatches()

Returns: PowerCC26X2_ResetReason

§ PowerCC26X2_releaseLatches()

static void PowerCC26X2_releaseLatches ( void )

inlinestatic

Unlatch all IOs.

This function releases the latches on all frozen IOs. This function should be called after waking up from shutdown and reconfiguring the IO state so as not to cause glitches.

Note: Calling this function will clear the reset reason register if it was PowerCC26X2_RESET_SHUTDOWN_IO and cause PowerCC26X2_getResetReason not to return the true reset reason.

Precondition: Power_shutdown(); PowerCC26X2_getResetReason()
