by my count you have asked this question at least 3 times. you probably haven't received a response due to one of the following reasons : 1. Nobody knows the answer. 2. No one has time to answer your question, since you ask simple questions that can be found if you read and understood the documentation. You have posted 44 times this year with questions, most of which are marked urgent. 3. Nobody can understand your question. I do realize that English is not your native language but most of your messages contain very little information about exactly what you are trying to do. as far as you question, based on what I think your question is, the QADC can operate in many modes and they can either be single scan or continuous scan. Continuous scan - the queue runs repetitively once started Single scan - the queue runs 1 time once started. The QADC can then be triggered to start by one of the following modes Software Trigger - Software begins the queue running External Trigger - an external event causes the queue to start (from either ETRIG1 or ETRIG2) External gated mode - queue runs while the trigger is present and stops when the trigger negates. Periodic or interval timer - the QADC has its own interval/periodic times that can be used to trigger conversions in the range of 128 to 128K QCLK cycles. this is interval or period is selectable. none of your messages mention which device you are using, but see section 14.4.4 "Scan modes" of the MPC561/MPC563 Reference Manual. the other devices (MPC555 and MPC565 have the same sections, but will be numbered differently). randy -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of G.V.Sasanka I want to know how to configure periodic interval timer for periodic conversion.If anyone has a code regarding this I shall be grateful..else i need the methedology to configure periodic interval timer..is it same as periodic interrupt timer??Also I shall be happy if someone can clarify me regarding my earlier mail too.
