Numbers
All
numbers
are
expressed
in
decimal,
except
addresses
and
memory
or
register
data,
which
are
expressed
in
hexadecimal.
Where
confusion
may
occur,
decimal
numbers
have
a
‘D’
subscript
and
binary
numbers
have
a
‘b’
subscript.
The
prefix
‘0x’
shows
a
hexadecimal
number,
following
the
‘C’
programming
language
convention.
Thus:
One
dozen
=
12D
=
0x0C
=
1100b
The
multipliers
‘k’,
‘M’
and
‘G’
have
their
conventional
scientific
and
engineering
meanings
of
*10
3
,
*10
6
and
*10
9
respectively.
The
only
exception
to
this
is
in
the
description
of
the
size
of
memory
areas,
when
‘K’,
‘M’
and
‘G’
mean
*2
10
,
*2
20
and
*2
30
respectively.
NOTE
When describing transfer rates, ‘k’, ‘M’ and ‘G’ mean *10
3
, *10
6
and *10
9
not
*2
10
, *2
20
and *2
30
.
Multiple
bit
fields
are
numbered
from
0
to
n,
where
0
is
the
LSB
and
n
is
the
MSB.
Text
Signal
names
ending
with
a
tilde
(~)
denote
active
low
signals;
all
other
signals
are
active
high.
