LOw power halt mode fail

[FLast.11]

void main(void)
{	
	clock_setup();
	GPIO_Config();
	
	CLK->ICKCR |= 0x10;//SAHALT; //0.03ma
	CLK_HaltConfig(CLK_Halt_FastWakeup,ENABLE);
	FLASH_PowerWaitModeConfig(FLASH_Power_IDDQ);
	PWR_UltraLowPowerCmd(ENABLE); // no diff
	FLASH_PowerWaitModeConfig(FLASH_Power_IDDQ);//no diff
	disableInterrupts(); //no diff
 
	halt(); 
	while(1)	
{
	//halt(); 
}

i have try using stvd to develope stml052R8

while i am using the halt mode to make it in the LOWest power consumption mode, however, i measure the current there 's still 0.08ma ...

can anyone suggest or pinpointing my problem?

thanks
