SPC560D30L3串行驱动程序配置问题

我使用的是带有8MHz晶振的SPC560D30L3。初始化设置如下，

1. IDF = 1
2. NDIV = 48
3. ODF = ODF_DIV8

我已将串行配置为38400波特，缓冲区为16个字节。我试图从PC发送一个7字节的帧（使用超级终端或类似的终端实用程序）。我观察到的是我只接收7个中的2个字节 - 第一个和最后一个，在字节之间丢失。问题是什么？是否缺少任何设置？

收到的两个字节是正确的，因此我对波特率设置毫无疑问。我对么？我尝试了不同的波特设置，但观察结果相同。可能是什么问题呢？

通过选择配置 - ＆gt;标识 - ＆gt;电路板标识符和电路板名称为“SPC56D_DISCOVERY”和“STMicroelectronics SPC56D Discovery”与“通用SPC56D电路板”的值相比，配置是否存在差异？我观察到两种设置的默认时钟设置不同。第一个提供XOSC时钟为16MHz，通用提供为8MHz。是否有任何配置更改？为什么会这样？

您在这方面的最早帮助将受到高度赞赏。提前致谢。

I am using SPC560D30L3 with 8MHz crystal. The initialisation settings are as below,

1. IDF = 1
2. NDIV = 48
3. ODF = ODF_DIV8

I have configured the serial for 38400 baud with buffer for 16 bytes. I am trying to send a frame of 7 bytes from PC (using hyperterminal or similar terminal utility). What I have observed is I am receiving only 2 bytes out of 7 - the first and last, in between bytes are lost. What is the problem? Are any setting missing?

The two bytes received are correct, hence I have little doubt for baud setting. Am I correct? I tried different baud settings but same observations. What could be the problem?

Is there any difference in configuration by selecting the Configuration->Identification->Board Identifier and Board Name as 'SPC56D_DISCOVERY' and 'STMicroelectronics SPC56D Discovery' as against the value 'generic SPC56D board'? I have observed that default clock settings differ between the two settings. First one gives XOSC clock as 16MHz and generic gives as 8MHz. Are there any configuration changes? Why these are so?

Your earliest help in this regard will be highly appreciated. Thanks in advance.
Mike.
