ADCSR
is
the
control
and
status
register
for
AD
converter.
ACH[2:0]
is
used
for
selection
of
the
analog
input
channel.
CKS[1:0]
is
used
for
selection
of
the
AD
converter
input
clock.
When
these
signals
are
ë00í,
the
main
clock
of
the
A/D
converter
is
1/8
times
of
input
clock
(ADCLK),
which
is
the
same
cycle
with
the
system
operation
clock..
When
these
signals
are
ë01í,
then
the
main
clock
of
the
A/D
converter
is
1/4
times
of
ADCLK.
When
these
signals
are
ë10í,
then
the
main
clock
of
the
A/D
converter
is
1/2
times
of
ADCLK.
When
these
signals
are
ë11í,
then
the
main
clock
of
the
A/D
converter
is
external
clock
from
Timer
block.
ADIE
bit
is
interrupt
enable
signal.
When
this
signal
is
ë0í,
then
A/D
converter
does
not
generate
the
interrupt
of
the
end
of
A/D
conversion.
When
this
signal
is
ë1í,
then
A/D
converter
generates
the
end
of
conversion
interrupt.
ADST
bit
indicate
the
start
of
A/D
conversion.
When
this
signal
is
ë1í,
the
A/D
converter
start
the
A/D
conversion
and
remain
high
during
A/D
conversion.
ADF
indicate
the
end
of
A/D
conversion.
When
this
bit
is
ë1í,
then
A/D
converter
indicates
the
end
of
A/D
conversion.
This
signal
is
auto-cleared
by

AIOSTOP
is
used
to
set
the
power

of
A/D
converter.
When
this
signal
is
ë0í,
then
A/D

is
entering
normal
