Requirements for Changing PULSAR Clock Frequency
MCU_R5FSS supports either 1 GHZ or 333 MHz for its core speed, and the interface clock is fixed at 333MHz. Core frequency switching between 1 GHz and 333 MHz is controlled through a CTRL_MMR bit to change the core to interface clock ratio from 3:1 to 1:1. The below software sequence shall be followed to prevent clock misalignment:
