The P2041 and T1040 reference manuals specifically say that the MPIC input clock is the platform clock/2.  The T2080 reference manual does not say this, but we have been assuming that is still the case.  Is this true? P2041RM … 23.3.20 Timer control register [Group A] (MPIC_TCRA) The TCR registers provide various configuration options such as count frequency and roll-over behavior for the timers. MPIC Memory Map P2040 QorIQ Integrated Multicore Communication Processor Family Reference Manual, Rev. 3, 6/2013 1702 Freescale Semiconductor, Inc. There are two choices for the clock source for the timers: a selectable frequency ratio from the MPIC input clock (platform clock/2) , or the RTC signal. T1040RM … 25.3.20 Timer control register [Group A] (MPIC_TCRA) The TCR registers provide various configuration options such as count frequency and roll-over behavior for the timers. MPIC Memory Map QorIQ T1040 Reference Manual, Rev. 0, 01/2015 1246 Freescale Semiconductor, Inc. There are two choices for the clock source for the timers: a selectable frequency ratio from the MPIC input clock (platform clock by 2), or the RTC signal. T2080RM … 25.5.22 Timer control register [Group n] (MPIC_TCRn) The TCR registers provide various configuration options such as count frequency and roll-over behavior for the timers. There are two choices for the clock source for the timers: a selectable frequency ratio from the MPIC input clock, or the RTC signal. Thanks!
