The Power Management Controller provides 3 main application modes.
• PLLA and UPLL are running respectively at 400 MHz and 480 MHz
• USB Device High Speed and Host EHCI High Speed operations are allowed
• Full Speed OHCI input clock is UPLLCK, USBDIV is 9 (division by 10)
• System Input clock is PLLACK, PCK is 400 MHz
• MDIV is ‘11’, MCK is 133 MHz
• DDR2 can be used at up to 133 MHz
• Only UPLL is running at 480 MHz, PLLA power consumption is saved
• USB Device High Speed and Host EHCI High Speed operations are allowed
• Full Speed OHCI input clock is UPLLCK, USBDIV is 9 (division by 10)
• System Input clock is UPLLCK, Prescaler is 2, PCK is 240 MHz
