24 / 50 page ![]() MPC5533 Microcontroller Data Sheet, Rev. 0.0 Electrical Characteristics Freescale Semiconductor 24 Table 16 shows the FLASH_BIU settings versus frequency of operation. Refer to the device reference manual for definitions of these bit fields. Table 16. FLASH_BIU Settings vs. Frequency of Operation1 1 Illegal combinations exist. Use entries from the same row in this table. Target Maximum Frequency (MHz) APC RWSC WWSC DPFEN 2 2 For maximum flash performance, set to 0b1. IPFEN 2 PFLIM 3 3 For maximum flash performance, set to 0b010. BFEN 2 Up to and including 27 MHz 4, 5 4 27 MHz parts allow for 25 MHz system clock + 2% frequency modulation (FM). 5 The APC, RWSC, and WWSC combination requires setting the PRD bit to 1 in the flash MCR register. 0b000 0b000 0b01 0b0 0b1 0b0 0b1 0b000 to 0b010 0b0 0b1 Up to and including 52 MHz 6 6 52 MHz parts allow for 50 MHz system clock + 2% FM. 0b001 0b001 0b01 0b0 0b1 0b0 0b1 0b000 to 0b010 0b0 0b1 Up to and including 77 MHz 7 7 77 MHz parts allow for 75 MHz system clock + 2% FM. 0b010 0b010 0b01 0b0 0b1 0b0 0b1 0b000 to 0b010 0b0 0b1 Up to and including 82 MHz 8 8 82 MHz parts allow for 80 MHz system clock + 2% FM. 0b011 0b011 0b01 0b0 0b1 0b0 0b1 0b000 to 0b010 0b0 0b1 Reset values: 0b111 0b111 0b11 0b0 0b0 0b000 0b0 |
