NOTES:
1
.
CCLK
is
an
internal
signal
not
seen
by
the
user.
2
.
The
next
command
can
be
initiated
during
the
cycle
t
6.
Two
dead
cycles
are
inserted
because
a)
write
commands
require
one
dead
cycle
before
the
next
instruction
initiates,
and
b)
the
second
cycles
insures
that
no
contention
occurs
on
the
SRAM
Data
Bus.
If
the
next
command
is
an
IPC
Read
,IPC
Write
or
SRAM
Write,
it
can
be
initiated
on
the
cycle
t
4.

.
The
Index
Bus
is
driven,
but
to
an
indeterminate
state.

For
ZBT,
the
OE
is
tied
LOW,
and
the

input
is
driven
by
the
IPC
