Sft system reset. (open-drain I/O)
Hard system reset. (open-drain I/O)
Suspends external bus activity. (open-drain I/O)
Indicates an erroneous bus operation is being attempted.
(open-drain I/O)
Internal system clock output 1. (O)
Internal system clock output 2—normally 2x CLKO1. (O)
Connections for an external crystal to the internal oscillator
circuit. EXTAL (I), XTAL (O).
Connection pin for an external capacitor to filter the circuit of
the PLL (I).
PINS SHOULD NOT BE SET TO 00
Indicates when the CPU32+ is performing an instruction
word prefetch (O) or input to the CPU32+ background debug
mode (I).
Used to track movement of words through the instruction
pipeline (O) or output from the CPU32+ background debug
mode (O).
Used to track movement of words through the instruction
pipeline (O), or a row address select 1 “double-drive” output
(O).
Signals a hardware breakpoint to the QUICC (open-drain I/
O), or clock signal for CPU32+ background debug mode (I).
Indicates that the CPU32+ has acknowledged a breakpoint
(O), or initial QUICC configuration select (I).
Used to three-state all pins if QUICC is configured as a mas-
ter. Sampled during system reset. (I)
Provides a clock for Scan test logic. (I)
Controls test mode operations. (I)
Serial test instructions and test data signal. (I)
Serial test instructions and test data signal. (O)
Provides an asynchronous reset to the test controller. (I)
