从user guide上看，msp430g2553的LFXT1仅支持低频模式（LF模式）。 那么，LFXT1可以接入的低频晶振范围呢？48kHz可以接入么？ |
LFXT1CLK: Low-frequency/high-frequency oscillator that can be used either with low-frequency 32768-Hz watch crystals, or standard crystals or resonators in the 450-kHz to 8-MHz range.
接更低的也行,,貌似32.768k能走自己制作RTC了.
MSP430G2553: 使用定时器TIMER1_A1模拟串行口时，看门狗复位时间就改变了MSP-GANG: 需要文档DRV9xxxx FLASH-Based Family User's Guide（SLAU532），非常感谢MSP-GANG: 需要下载这个文件：DRV9_patch_files.zip，谢谢
MSP430F2618: MSP430F2618芯片不使用外部LFXT1，振荡器一直报故障MSP430F6736: MSP430F6737上电有时候会报IEC60730 CRC test failureMSP430I2041TPWR 用SBW接口无法下载程序
MSP430F2618: DAC12 Fullscale range selection issue. (Power consumption of DAC12 module may be increased due to DAC12IR bit selection)
MSP430FR6043: FRAM 的0x6000-0x63FF段无法擦除
