MSP430F5438 ADC中SHI信号源



文档中有说明是

00 · The ADC12SC bit ·

01   The Timer_A Output Unit 1 ·

02   The Timer_B Output Unit 0 ·

03   The Timer_B Output Unit 1

1、现在的疑问是如果我选择01,那TA输出单元1代表的是TA0的输出单元1还是TA1的输出单元1?

2、TA中TAx,TAxCCRx代表是什么?

3、在msp430x54x.h文件中以下两句代码注释中Timer1_A3是什么?

#define TIMER1_A1_VECTOR    (48 * 2u) /* 0xFFE0 Timer1_A3 CC1-2, TA1 */

#define TIMER1_A0_VECTOR    (49 * 2u) /* 0xFFE2 Timer1_A3 CC0 */
