LM3S2965 - QIE0 Problem

Hi all,

I have problem with configuration of QIE0.

Because PHA0 is on PC4 and PHB0 is on PH3 so to configure gpio I use these two function below.

GPIOPinTypeQEI(GPIO_PORTC_BASE, GPIO_PIN_4);
GPIOPinTypeQEI(GPIO_PORTH_BASE, GPIO_PIN_3);

I found that second function hang uC.
Of course befor these two function I call:

SysCtlPeripheralEnable(SYSCTL_PERIPH_QEI0);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOG)

I'm little confused because QIE1 work just fine.
