2.3.2.31
External Bus Grant / GPIO
BG
_
GPIO[73]
BG_GPIO[73] is the bus grant.Because the BG primary signal function is reserved on this device, there is
no primary signal function for this ball. GPIO[72] pin has GPIO functionality only. These signals are not
supported in the 324 package.
2.3.3
Nexus Signals
2.3.3.1
Nexus Event In
EVTI
EVTI is an input that is read during a debug port reset to enable or disable the Nexus Auxiliary port for
data trace. After reset, the EVTI pin is used to initiate program and data trace synchronization messages
or generate a breakpoint.
2.3.3.2
Nexus Event Out
EVTO
EVTO is an output that provides timing to a development tool for a single watchpoint or breakpoint
occurrence.
2.3.3.3
Nexus Message Clock Out
MCKO
MCKO is a free running clock output to the development tools which is used for timing of the MDO and
MSEO signals.
2.3.3.4
Nexus Message Data Out
MDO[0]
MDO[0] is a trace message output to the development tools. In addition, MDO[0] indicates the lock status
of the system clock following a power-on reset. MDO[0] is driven high following a power-on-reset until
the system clock achieves lock, at which time it is then negated. There is an internal pullup on MDO[0].
2.3.3.5
Nexus Message Data Out
MDO[3:1]
MDO[3:1] are the trace message outputs to the development tools.
2.3.3.6
Nexus Message Data Out / GPIO
MDO[11:4]_GPIO[82:75]
MDO[11:4]_GPIO[82:75] are the trace message outputs to the development tools for full port mode. These
pins function as GPIO when the Nexus port controller (NPC) operates in reduced port mode.
