关于MSP430F5529捕获问题

Other Parts Discussed in Thread: MSP430F5529

你好,

用MSP430F5529芯片,P2.4/TA2.1作为信号源输入,最快1M的频率方波,由于工作电压的限制,主频只能调到4M工作,请问:

1. 用capture捕获功能可否不丢周期的检测到每个信号的周期?是不是可以将输入的信号源分频后再检测?

2.用捕获功能,对于这个脚是CCI1A的的输入,请问我需要设置哪个寄存器来确定是这个引脚作为捕获信号功能:TA0CCTL1,TA1CCTL1,TA2CCTL1,还是其他的?

3.进中断的话,是哪个中断:

TIMER0_A0_VECTOR,TIMER0_A1_VECTOR

TIMER1_A0_VECTOR,TIMER1_A1_VECTOR

TIMER2_A0_VECTOR,TIMER2_A1_VECTOR

谢谢!
