Bus Lock
prevents other system bus masters from gaining
control of the system bus while it is active (low).
Memory/IO
indicates whether the current bus cycle is a mem-
ory cycle or an input/output cycle. When M/IO# is high, the
bus cycle is a memory cycle; when M/IO# is low, the bus cycle
is an I/O cycle.
Next Address
requests address pipelining.
No Connection
should always be left unconnected. Connect-
ing a NC pin may cause the processor to malfunction or cause
your application to be
incompatible with future steppings of
the device.
Nonmaskable Interrupt Request
is a nonmaskable input
that causes the CPU to suspend execution of the current pro-
gram and execute an interrupt acknowledge function.
Processor Extension Request
indicates that the math
coprocessor has data to transfer to the processor.
Bus Ready
indicates that the current bus cycle is finished and
the external device is ready to accept more data from the pro-
cessor.
Reset
suspends any operation in progress and places the
processor into a known reset state.
Write/Read
indicates whether the current bus cycle is a write
cycle or a read cycle. When W/R# is high, the bus cycle is a
write cycle; when W/R# is low, it is a read cycle.
System Power
provides the nominal DC supply input.
