Doubt with the ADC convertion time in MPC5604B

Question asked by Andres Torres Garcia on Jun 6, 2012

Hi, someone knows how to configure the CTR register to make the ADC convertion time in 1 us?. with the analog clock in 32MHZ


In the examples; they configured with this value: 0x00008606. Making the calculations with this configuration we have:


40*Tck = 40 * 1/32 = 1.25 us


And the result is not 1 us……..


In the reference manual says that the minimum convertion time was 1 us, but in the page 728 under the table says "“The ADC minimum conversion time at 60 MHz frequency is 39 * Tck; that corresponds to 650 ns". This is contradictory, isn't it?


Can you help me?


Best Regards,
