Selects the source of the internal system clock upon reset
or becomes a parallel I/O port
Indicates when the CPU32 is performing an instruction
word prefetch and when the instruction pipeline has been
flushed or provides background debug mode serial in
Used to track movement of words through the instruction
pipeline or provides background debug mode serial out
Signals a hardware breakpoint to the CPU32 or provides
background debug mode serial clock
Indicates that the CPU32 has entered background debug
mode
Transmitter serial data output from the serial module
Serial module clear-to-send inputs
Channel request-to-send outputs or discrete outputs
Connections for an external crystal to the serial module
internal oscillator circuit
External serial module clock input
Indicates transmit buffer has a character or becomes a
parallel output
Indicates receive buffer has a character, the receiver
FIFO buffer is full or becomes a parallel output
Input that starts a DMA process
Output that signals an access during DMA
Bi-directional signal that indicates the last transfer
Counter enable input to timer
Time reference input to timer
Output waveform from timer
Controls test mode operations
Shifts in instructions and test data
Shifts out instructions and test data
Quiet power supply to VCO; also used to control
synthesizer mode after reset.
Power supply and ground to the MC68340
Provides a clock for IEEE 1149.1 test logic
