stm32l152V8t6 pb4-lcdseg8

Hi,

I'm using the emdedded stm32l lcd driver on the stm32L152V8t6 (lqfp 100pin)
 
all segments work well,but on the pb4-lcdseg8 I see a fixed voltage level(about 2.9V)
very near to the vdd voltage.

the lcd glass is ok.

or the stm32l152v8t6 has the pb4-lcdseg8 driver broken or there is an error on the datasheet.

Can someone confirm me that this pin is working as lcd seg driver ?

the following is the port initialization:

 

/* GPIO PB4 LCDSEG8 */

 

GPIO_InitStructure.

GPIO_Pin = GPIO_Pin_4;
GPIO_InitStructure.
GPIO_Mode = GPIO_Mode_AF;
GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_PinAFConfig(GPIOB, GPIO_PinSource4,GPIO_AF_LCD) ;


Thanks in advance
