enum UART_FIFOSIZE
{
UART_FIFOSIZE_16,

But it's not used.

还有一个UART2_Handler_func方法，似乎没有定义任何地方。谁能解释一下这是怎么安排的，所以我可以使用它正确吗? < / p > < p > < br / >感谢Ankit < / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / uart2 typeof =“skos:概念”属性= " rdfs: label skos: prefLabel”数据类型= " " > uart2 < / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords / isr”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > isr < / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords /中断”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >中断< / > < / div > < div class = " field-item古怪”> < a href = " / resource-keywords /处理程序”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " >处理< / > < / div > < div class =”field-item甚至“> < a href = " / resource-keywords / da14580-uart”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > DA14580UART < / > < / div > < / div > < / div > < div class =”字段field-name-field-device field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >设备:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / forum-post-device / da14580”“=“skos:概念”属性=“rdfs: label skos: prefLabel”数据类型= " " > DA14580 < / > < / div > < / div > < / div > 2015年9月24日星期四13:29:28 +0000 ankitdaf 2039年https://support.dialog-semiconductor.com https://support.dialog-semiconductor.com/how-does-uart2-rx-interrupt-work#comments
