CLEAR_BIT(RCC->CIER, (__INTERRUPT__))

Disable RCC interrupt(s).

Parameters:

__INTERRUPT__

specifies the RCC interrupt source(s) to be disabled. This parameter can be any combination of the following values: RCC_IT_LSIRDY LSI ready interrupt RCC_IT_LSERDY LSE ready interrupt RCC_IT_MSIRDY HSI ready interrupt RCC_IT_HSIRDY HSI ready interrupt RCC_IT_HSERDY HSE ready interrupt RCC_IT_PLLRDY Main PLL ready interrupt RCC_IT_PLLSAI1RDY PLLSAI1 ready interrupt for devices with PLLSAI1 RCC_IT_PLLSAI2RDY PLLSAI2 ready interrupt for devices with PLLSAI2 RCC_IT_LSECSS LSE Clock security system interrupt RCC_IT_HSI48RDY HSI48 ready interrupt for devices with HSI48
