Table 11.3 Operating Frequency and Voltage Ranges in Operating Power Control Modes
Operating
Operating Power OPCM Voltage
Control Mode [2:0] Bits Range
High-speed 000b 2.7 to 5.5 V
operating mode
Middle-speed 010b 2.7 to 5.5 V
operating mode
Note: When using the FCLK at lower than 4 MHz during programming or erasing the flash memory, the frequency can be set to 1, 2,
or 3 MHz.
Each operating power control mode is described below.
 High-Speed Operating Mode
The maximum operating frequency during FLASH read is 32 MHz for ICLK, FCLK, PCLKB, and PCLKD.
During FLASH programming/erasure, the operating frequency range is 1 to 32 MHz.
Note: When using the FCLK at lower than 4 MHz during programming or erasing the flash memory, the frequency can
be set to 1, 2, or 3 MHz.
 Middle-Speed Operating Mode
As compared to high-speed operating mode, this mode reduces power consumption for low-speed operation.
The maximum operating frequency during FLASH read is 12 MHz for ICLK, FCLK, PCLKB, and PCLKD.
During FLASH programming/erasure, the operating frequency range is 1 to 12 MHz.
The power consumption of this mode is lower than that of high speed mode under the same conditions.
After a reset is canceled, operation is started from this mode.
Note: When using the FCLK at lower than 4 MHz during programming or erasing the flash memory, the frequency can
be set to 1, 2, or 3 MHz.
