The following setup was used to measure the open loop voltage gain for crystal
oscillator circuits. The feedback resistor serves to bias the circuit at its quiescent
operating point and the AC coupling capacitor, Cs, is much larger than C1 and C2.

Table 5.5 Behavior Description
Power Saving Mode Test item Expected Behavior
1. Host is in normal
mode. While there is no
card inserted, plug
AU9540 into host.
AU9540 will be in suspending
mode. Host will not detect
AU9540.
2. Host is in normal
mode. While there is
card inserted, plug
AU9540 into host.
A
U9540 will be detected by the
host and ready to operate
smart card.
3. Host is in normal
mode. When AU9540 is
connected to the host
and there is card
inserted in the slot, plug
off the card and plug in it
again.
When the card is removed,
A
U9540 will be forced into
suspend mode. Host will detect
that AU9540 is removed. When
the card is inserted again,
A
U9540 will be detected by the
host again.
Under power saving
mode, when the card is
removed, the USB
connection of AU9540 will
be disconnected from
host. If the card is
inserted, then AU9540 will
be connected to the host.
4.
When AU9540 is not
inserted into the host
and host is in suspend
mode, make sure there
is no card inserted into
A
U9540 and plug
Host will not detect AU9540.
And host will not be woken up.
AU9540 USB Smart Card Reader V1.6
11
AU9540 into the host.
5. When AU9540 is not
inserted into the host
and the host is in
suspend mode. Plug
A
U9540 into the host
with smart card inserted
in advance.
Host will be woken up and
detect AU9540. After the host
is woken up, AU9540 is ready
to operate card now.
6. When AU9540 is
inserted into the host,
insert a smart card into
A
U9540. Then get host
into suspend mode.
A
fter that, remove the
smart card from
A
U9540. Then plug in
the smart card again.
When user removes the card, it
will not wake up the host from
suspend mode. Then insert a
card. It will wake up the host.
A
fter the host is woken up,
A
U9540 will be ready to
operate the card.
7. When there is no card
inserted into AU9540
and the host is in
suspend mode, plug
A
U9540 into the host.
Then, insert a smart
card into AU9540.
When AU9540 is plugged into
the host without card inserted,
the host will not be woken up.
However, if user inserts a card
now, the host will be woken up.
This feature must work with
host system that supports
remote-wake up.
6. USB Selective Suspend Feature
The driver determines whether it should enter selective suspend state by the following
requirements.
1. The card is in power off state or there is no card in the reader.
2. The reader is idle at least for a given time (30 seconds by default). It means during
the period there is no command issuing to reader and there is no card
inserting/removing event occurs.
When the driver detects both the two requirements above are met, it starts processing
the following tasks,
1. Send standard USB command to the reader to enable remote wake function.
2. Start selective-suspend procedure to ask the system to suspend the reader.
After entering the selective suspend state, the driver determines whether it should exit
selective suspend state when one of the following conditions occurs,
1. There is any command which intend to communicate with the reader.
2. When card inserting/removing event occurs, the reader issues resume signal to the
host. Then the system will inform the driver to exit selective suspend state.
