Is Periodic Interrupt Timer and Enhanced Capture Timer both are different

[kdn]

if is different then how can I configure Periodic Interrupt Timer in processor expert for MC9S12XHZ512

Hi,

For periodic interrupts, you can use Periodic Interrupt Timer (PIT), Enhanced Capture Timer (ECT) or Real Time Interrupt (RTI, part of CRG module).

In attachment you can find simple example codes which generate periodic interrupt.

Note: Example code does not use PE.

Note: Example code was designed for S12XD family however behavior should be the same also for S12XHZ.

Note: Result periods will depend on frequency of your clock source.

I hope it helps you.

Have a great day,
RadekS
