是的，这段代码使用了16位传输。如果想一次传输8位数据，可以将代码修改为：

__data16_write_addr((unsigned short) &DMA0SA,(unsigned long) sin_table); // Source block address __data16_write_addr((unsigned short) &DMA0DA,(unsigned long) &UCA1TXBUF); DMA0SZ = 8; // Set transfer size to 8 bytes (1 byte = 8 bits)

__data16_write_addrunsigned short &DMA0SAunsigned long sin_table; Source block address __data16_write_addrunsigned short &DMA0DAunsigned long &UCA1TXBU
