I wanna ask a question. When I try to set frequency to 100 MHz (MPC5644A), I don't success. But if I try to set frequency up to 82 MHz, there is no problem.
I see some examples project which include following definitions (" #define FLASH_REG FLASHA.BIUCR.R "and " #define FLASH_DATA 0x00018C55")
There is no information about these definitions on DataSheet for MPC5644A. Do you think this is real reason ? (When I add these definitons I can set high frequencies)
