MSP430F248 TIMER CLOCK DIVIDER - erde...@yahoo.com - Sep 7 5:59:33 2009
Hi,
I am using timer A0 and timer A2 individually as input clock divider is 1. In this way they are working correctly. But; when i use them both the input clock is divided by 2. Why may that be?

Most likely, something (or someone) is wrong.

It seems, something is wrong.

It is quite possible that something is wrong.
But very often, someone thinks something is wrong even when it is not.

A0 and A2 are not different timers, they're different capture/compare modules associated to the same TimerA.

The only way to know that is to look at the clock divider bits in the TACTL register. Does it indicate a division by 2? Else your are only making a wrong assumption.
Start by reading the entire TimerA chapter from top to bottom. If still in doubt come back with a specific question and as we are not telepathic, give us more information about your setting (the setup code for example?).

Hi,
I recognized that i had some conflicts about timer_A module and i solved my problems, so no more problem with timer_A. Thanks guys.
