Summary

Declaration

from stm32f4xx_hal_irda.h:499

#define __HAL_IRDA_GET_IT_SOURCE(__HANDLE__, __IT__) (((((__IT__) >> 28U) == IRDA_CR1_REG_INDEX)? (__HANDLE__)->Instance->CR1:(((((uint32_t)(__IT__)) >> 28U) == IRDA_CR2_REG_INDEX)? \ (__HANDLE__)->Instance->CR2 : (__HANDLE__)->Instance->CR3)) & (((uint32_t)(__IT__)) & IRDA_IT_MASK))

Arguments

Argument

Description

__HANDLE__

specifies the IRDA Handle. IRDA Handle selects the USARTx or UARTy peripheral (USART,UART availability and x,y values depending on device).

__IT__

specifies the IRDA interrupt source to check. This parameter can be one of the following values: @arg IRDA_IT_TXE: Transmit Data Register empty interrupt @arg IRDA_IT_TC: Transmission complete interrupt @arg IRDA_IT_RXNE: Receive Data register not empty interrupt @arg IRDA_IT_IDLE: Idle line detection interrupt @arg IRDA_IT_ERR: Error interrupt @arg IRDA_IT_PE: Parity Error interrupt
