您好,看到TI的说明书有下面一段
XIN and XOUT pins are set to general-purpose I/Os and XT1 remains disabled until the I/O ports are
configured for XT1 operation.
• When available, XT2IN and XT2OUT pins are set to general-purpose I/Os and XT2 is disabled.
As previously stated, FLL operation with XT1 is selected by default, but XT1 is disabled. The crystal pins
(XIN, XOUT) are shared with general-purpose I/Os. To enable XT1, the PSEL bits associated with the
crystal pins must be set.
请问msp430F6726的XIN and XOUT和P口复用吗?要设置PSEL吗?
还有msp430F6726的AUXVCC1、AUXVCC2、AUXVCC3接地,VDSYS、VASYS、DVSYS通过电容接地,VDSYS、VASYS、DVSYS不接电源可以吗?
