Type
SysClock
Input
Table 7 Interrupt Interface
Pin Name
Int[5:0]*
Table 8 JTAG Interface
Pin Name
JTDI
Description
System Clock
Master clock input used as the system interface reference clock. All
output timings are relative to this input clock. Pipeline operation
frequency is derived by multiplying this clock up by the factor selected
during boot initialization
Quiet Vcc for PLL
Quiet Vcc for the internal phase locked loop. Must be connected to
VccInt through a filter circuit.
Quiet Vss for PLL
Quiet Vss for the internal phase locked loop. Must be connected to Vss
through a filter circuit.
