In this code,

I understand the line

''EXTI_SetExtIntSensitivity(EXTI_PORT_GPIOB , EXTI_SENSITIVITY_FALL_ONLY);''

It means EXTI detects falling edge, right?

But what's the next line means??

''EXTI_SetTLISensitivity(EXTI_TLISENSITIVITY_FALL_ONLY);'' 

I read the reference manual about EXTI section but there is no enough information about TLIS..

the note you showed up says it clearly: it is the sensitivity for the TLI pin.

I understand, this pin PD7 cannot be acting with interrupt in the same time with PD0,PD1...6. Is it correct?
