Function Name

TIM_ITConfig

Function Prototype

void TIM_ITConfig (TIM_TypeDef *TIMx,

u16 New_IT, FunctionalState NewState);

Behavior Description

This routine is used to configure the TIM interrupt.

Input Parameter 1

TIMx: specifies the TIM to be configured. Refer to TIM values on

page 103 for more details on the allowed values of this parameter.

Input Parameter 2

New_IT: specifies the TIM interrupt to be configured. You can specify
