I
Soft (Warm) Reset
This signal must be asserted synchronously with MasterClock for a soft reset.
Cold reset
This signal indicates to the processor that the +3.3V power supply is stable and
the processor should initiate a cold reset sequence, resetting the PLL.
64-bit external bus mode
Indicates the initial setting of the bus size during a reset.
0
64-bit mode
1
32-bit mode
PLL connect to capacitor
A capacitor is connected between PLLCAP and the VccPLL to ensure the
proper operation of the phase-locked loop.
