B. The PCI peripheral pins are muxed with some of the HPI peripheral pins and the UTOPIA address pins. For more detailed information, see the
Device
Configuration
section of this document.
C. Each of the TIMER peripherals (TIMER1 and TIMER0) is configurable as either two 64-bit general-purpose timers
or
two 32-bit general-purpose
timers
or
a watchdog timer.
D. The PLL2 controller also generates clocks for the EMAC.
E. When accessing the internal ROM of the DSP, the CPU frequency must always be less than 750 MHz.
