No UDP HS, UHP FS and DDR2 Mode
• Only PLLA is running at 384 MHz, UPLL power consumption is saved
• USB Device High Speed and Host EHCI High Speed operations are NOT allowed
• Full Speed OHCI input clock is PLLACK, USBDIV is 7 (division by 8)
• System Input clock is PLLACK, PCK is 384 MHz
• MDIV is ‘11’, MCK is 128 MHz
• DDR2 can be used at up to 128 MHz
• Includes a 20-bit Periodic Counter, with less than 1µs accuracy
• Includes a 12-bit Interval Overlay Counter
• Real Time OS or Linux/WinCE compliant tick generator
• 16-bit key-protected only-once-Programmable Counter
