Hello everyone,

I have a general question. I am using the ECT timer in MC9S12XET256. To enable the timer I set the TSCR1 to 0x80 (setting 1 to the TEN bit).

My question is, if I were to set the timer enable multiple time without disabling the timer in between, like below, is there any side-effect in terms of timer accuracy etc...?


ECT_TSCR1 = 0x80   //enable timer

//do something

ECT_TSCR1 = 0x80




Thanks for replying.


Yours sincerely,
