12.1(BUS
Interface)
Name
I/O
Function
nRESET
I
These
signal
indicate
the
reset
status
of
the
ASB
BCLK
I
The
ASB
clock
timing
all
bus
transfers
DSELREG
I
When
this
signal
is
HIGH,
it
indicates
that
the
Flash
Memory
configuration
Internal
registers
are
selected.
(When
BA[31:0]
is
set
to
FMI
Region,
0x09000200~0x090002ff,
of
Memory
Map)
DSEL
I
When
this
signal
is
HIGH,
it
indicates
that
the
Flash
Memory
Array
address
is
selected.
(When
BA[31:0]
is
set
to
Flash
Memory
Region
of
Memory
Map.)
BWRITE
I
When
this
signal
is
HIGH,
it
indicates
a
write
transfer
and
when
LOW
a
read.
BSIZE[1:0]
I
These
signals
indicate
the
size
of
the
transfer
that
may
be
byte,
half-
word,
or
word.
BA[31:0]
I
System
address
bus.
BA[[31:17]
is
used
for
selection
between
Internal
Register
Block
and
Flash
Memory.
BA[16:0]
is
used
for
selection
of
Specific
Internal
Register
or
Flash
Memory
Address.
BD[31:0]
I/O
Bi-directional
system
data
bus.
BWAIT
O
Wait
slave
response
signal.
It
is
driven
to
phase
1
when
Flash
Memory
Read
operation
is
selected.
It
is
asserted
while
the
Flash
Memory
Read
operation
is
uncompleted.
BERROR
O
When
BEEOR
is
HIGH,
a
transfer
error
has
occurred.
When
BERROR
is
LOW,
then
the
transfer
is
successful
BLAST
O
When
BLAST
is
HIGH,
the
system
decoder
must
allow
sufficient
time
for
address
decoding.
When
BLAST
is
LOW,
the
next
transfer
may
continue
a
burst
sequence.
MODE
[2:0]
I
These
signals
are
directly
connected
to
external
pins(MD
2
~
MD
0
),
and
represent
operating
mode
at
Table12.1
FTVPPD
In
It
is
external
power
that
is
used
to
flash
memory
program
and
directly
Connected
to
external
pin
at
all
operating
mode.
