宏定义说明

ITM_RXBUFFER_EMPTY

#define ITM_RXBUFFER_EMPTY   ((int32_t)0x5AA55AA5U)

Value identifying ITM_RxBuffer is ready for next character.

函数说明

ITM_CheckChar()

__STATIC_INLINE int32_t ITM_CheckChar

(

void

)

ITM Check Character

Checks whether a character is pending for reading in the variable ITM_RxBuffer.

返回
