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.
Interrupt
Six general processor interrupts, bit-wise ORed with bits 5:0 of the
interrupt register.
Non-maskable interrupt, ORed with bit 6 of the interrupt register.
JTAG data in
JTAG serial data in.
JTAG clock input
JTAG serial clock input.
JTAG data out
JTAG serial data out.
JTAG command
JTAG command signal, signals that the incoming serial data is
command data.
Non-maskable interrupt
