Breakpoint and Performance Monitor Signals: Outputs
from the processor that indicate the status of
breakpoints and programmable counters used for
monitoring processor performance.
I/O
GTL
DBR#
DBR# is used only in systems where no debug port is
implemented on the system board. DBR# is used by a
debug port interposer so that an in-target probe can
drive system reset.
O
PRDY#
PRDY# is a processor output used by debug tools to
determine processor debug readiness.
O
Asynch
GTL
PREQ#
PREQ# is used by debug tools to request debug
operation of the processor.
I
Asynch
GTL
TCK
TCK (Test Clock) provides the clock input for the
processor Test Bus (also known as the Test Access Port).
I
TAP
TDI
TDI (Test Data In) transfers serial test data into the
processor. TDI provides the serial input needed for JTAG
specification support.
I
TAP
TDI_M
TDI_M (Test Data In) transfers serial test data into the
processor. TDI_M provides the serial input needed for
JTAG specification support.
I
TAP
TDO
TDO (Test Data Out) transfers serial test data out of the
processor. TDO provides the serial output needed for
JTAG specification support.
O
TAP
TDO_M
TDO_M (Test Data Out) transfers serial test data out of
the processor. TDO_M provides the serial output needed
for JTAG specification support.
O
TAP
TMS
TMS (Test Mode Select) is a JTAG specification support
signal used by debug tools.
I
TAP
TRST#
TRST# (Test Reset) resets the Test Access Port (TAP)
logic. TRST# must be driven low during power on Reset.
