MSP430 eusci波特率计算问题

参考程序中的说明

//! Is Second modulation stage register setting. This value is a pre-
//! calculated value which can be obtained from the Device Users Guide.
//! This value is written into UCBRSx bits of UCAxMCTLW.
uint8_t secondModReg;

而

 32768/9600 - INT(32768/9600)=0.41
UCBRSx value 可以在用户指南中Table 30-4. UCBRSx Settings for Fractional Portion of N = fBRCLK/Baud Rate找到

0.4003 0x92

而0x92转换为十进制为146
