10.2.3 Controller
DS0200-003
There is one controller state machine in Smart Card 0 and four controller state machines in Smart Card 1 to
manage card power on, card cold and warm reset, and card deactivation stages. The Smart Card 1
multiplexer must be configured before each command to select the appropriate controller state machine via
SIM_SEL. The state diagram for the controller is shown below.
The states are described below:






Idle: After card detection (DET_CMD), software sets COMMAND.PWR_CARD to ‘1’ to power
up the card before changing to PowerCard. All outputs are in their inactive state.
PowerCard: The controller applies power. Software sets COMMAND.DEAC_CARD to ‘1’. It
is up to software to ensure power is stable before sending the CardReset command by reading
SCSTATUS. If the card is removed, the controller automatically returns to the Idle state.
ResetCard: On entering this state, the card clock is started, the card IO is ‘0’, the card reset is
asserted by the external interface device, and the reset duration counter is started. When the
counter reaches the count programmed in RST_LEN, the controller changes to
WaitCommand. If the card is removed anytime during the reset state the controller changes to
WaitDeactivation.
WaitCommand: On entering this state, card reset is set inactive and data transfers may occur.
When data transfer is complete, one of the following three commands can be issued.

o
If the card is removed during this state the controller automatically changes to the
WaitDeactivation state.
WaitDeactivation: On entering this state, the deactivation delay counter is started. When the
counter reaches the count programmed in DEAC_DLY, the controller moves to
DeacResetCard. It is up to the software to program the proper delay according to the protocol
or the current card session stage.
DeacResetCard: The external interface card reset is pulled ‘0’ and the controller moves to
DeacStopClock.
StopCardClock: The Smart Card clock is stopped.
DeactivateCard: The controller changes to WaitDeactivation.
ResetCard: The controller performs a warm reset of the card by changing to ResetCard.
