I am using the MPC555 variant MPC565, which has the ability to be sampled at up to 56 MHz. However, when I try to change the system clock to 56 MHz by setting USIU_PLPRCR_B_MF value to 13 in the MPC555 Resource Configuration block, I receive the following error:
Error evaluating 'InitFcn' callback of block_diagram 'untitled'. Error using ==> RTWConfigurationCB *** Resource Configuration Error *** The derived value for System_Clock is not in the range 1MHz to 40MHz. Exceeding 40MHz would result in overclocking the processor, and possible undeterministic behaviour. To fix this error, choose a valid set of values for the system frequency configuration registers
