RTC-only mode for C5532 ?

Pascal COINCE
Prodigy 200 points
Other Parts Discussed in Thread: TMS320C5532

Hi

I'm trying to get the RTC-only mode working on a TMS320C5532, but I'm not sure it is possible...

To do so, the datasheet says that the DSP_LDO_EN must be tied to GND: done, and an RTC alarm programmed to wake up the CPU: done. To enter RTC-only mode, bit LDO_PD or BG_PD must be set to 1 in RTCPMGT register: done.  But the CPU seems to freeze, with a power consumption not as low as I except.

Moreover the technical reference manual says that LDO_PD and BG_PD are reserved for future devices ??

Is it possible to use the RTC-only mode or not on a C5532 ?

Regards
