 NewState : new state of the specified peripheral clock. This
parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 After reset, the peripheral clock (used for registers read/write
access) is disabled and the application software has to enable
this clock before using it.
18.2.8.11 RCC_APB2PeriphClockCmd
Function Name
void RCC_APB2PeriphClockCmd ( uint32_t RCC_APB2Periph,
FunctionalState NewState)
Function Description
Enables or disables the High Speed APB (APB2) peripheral clock.
Parameters
 RCC_APB2Periph : specifies the APB2 peripheral to gates
its clock. This parameter can be any combination of the
following values:

 RCC_APB2Periph_TIM1 :
 RCC_APB2Periph_TIM8 :
 NewState : new state of the specified peripheral clock. This
parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 After reset, the peripheral clock (used for registers read/write
access) is disabled and the application software has to enable
this clock before using it.
