• MPC8535 Clocking Specific FAQs

    MPC8535 PCI controller can get clock from SYSCLK (synchronous) or from PCICLK (PCI asynchronous mode). If PCI is configured as PCI asynchronous mode, a valid clock must be provided on pin PCICLK, otherwise the process...

  • MPC8360 DDR Specific FAQs

    For MPC8360, is any way that the CPU can read and write the full 72-bit wide DDR memory bus, bypassing the ECC logic? I want to know if the memory controller can be configured for the 72-bit wide DDR memory bus to byp...

  • MPC8360 Clocking Specific FAQs

    MPC8360 H/W spec describes that Max SYSCLK frequency is 100MHz. Generically when user inputs 100MHz clock, actual clock speed become more faster. I think MPC8360 has enough margin for faster SYSCLK as long as I use up...

  • MPC8306/MPC8306S Hardware Specifications/Reference Manual Specific FAQs

    As MPC8306RM.pdf shows, one can multiplex some pins such as, LAD8/GE_PA0 multiplexing. My design uses LOCAL BUS (nor flash) and UTOPIA at the same time. Can I design my product like this in view of pin multiplexing? ...
