Hello

I'm trying to have the MCU in Active Halt mode and have it wake up by external interrupt or 512msec timeout.
I'm using a REva starter kit with:
- a REva motherboard v3.3 with RLink
- a REva STM8S208RB daughter board.
- Windows XP, Service Pack 3
- Ride Ver. 7.24.09.0251
- RKit-STM8 Ver. 2.24.09.0238
activated for 16K code.

I did the following:

during initialization of the clock -

CLK_DeInit();
CLK_HSIPrescalerConfig(CLK_PRESCALER_HSIDIV1);
CLK_FastHaltWakeUpCmd(ENABLE);
CLK->ICKR |= CLK_ICKR_LSIEN;
while (((CLK->ICKR) && 0x02) == 0)
_nop_();

Enabled interrupt from external push button, the interrupt does a XOR on output I/O pin.

just before the main loop of the application:

AWU_LSICalibrationConfig(128000);
AWU_Init(AWU_TIMEBASE_512MS ); //AWU_TIMEBASE_NO_IT);

somewhere at the main loop I put the halt command - "_halt_();"

when the debugger reaches the command I get "no response from the DTC, terminating debug session".
I figured the debugger might have lost communication with the MCU, so I tried running the MCU without the debugger but there is no response when I do an external interrupt (can't see the port change value).

It would have been great if the MCU can wake up from the Active Halt mode using internal interrupt from a timer, but if I understand correctly the timers are not functioning in that mode, so AWU will have to be used. other modes just take to much power.

appreciate any help
best regards
