28335的勘误手册上有如下说明：
Advisory： Memory: Possible Incorrect Operation of XINTF Module After Power Up
Revision(s) Affected 0, A
Details ：The XINTF module may not get reset properly upon power up. When this happens, accesses to XINTF addresses may cause the CPU to hang. This issue occurs only upon power up. It does not happen for other resets such as a reset initiated by the watchdog or an external (warm) reset using the XRS pin.
Workaround(s)： After coming out of reset, software should force a watchdog (WD) reset if WDFLAG = 0 in the WDCR register. WDFLAG = 0 implies that an external reset occurred, for example, a power-on reset. After exiting the WD reset, WDFLAG will be 1. In this case, software should clear the WDFLAG bit before continuing normal code execution. This issue affects only the XINTF module.
这条说明是指的28335自己内部的上电复位还是外部在上电后做的一次复位？仅仅对外部XRS复位管脚在上电后提供一次200ms的复位会不会产生上述问题？是要求对28335的外部复位管脚进行二次复位么？
