Configuring the clock for PIT

I'm still discovering the K20 chip using the Tower K20 demo kit with the demo_gpio project supplied by freescale.

I have set a PIT as described in this earlier topic:


I've left all the MCG config as is in the demo project.

the maximum tick frequency I can get with the PIT is around 2MHz, although the mcg_clk_hz is 72.000.000 (= core_clk)


Is this normal? I thought the max freq achievable with PIT should be half the core clock.
