Logic circuitry
After power-up, the circuit has six possible states of
operation. Figure 9 shows the state diagram.
I
After reset, the circuit enters the idle mode. A minimum
number of functions in the circuit are active while waiting
for the microcontroller to start a session:
L
When pin MODE goes LOW, the circuit enters the
low-power (sleep) mode. As long as pin MODE is LOW no
activation is possible.

DEACTIVATION

ACTIVATION
FAULT
If pin MODE goes LOW in the active mode, a normal
deactivation sequence is performed before entering the
low-power mode. When pin MODE goes HIGH, the circuit
enters the normal operating mode after a delay of at least
6 ms (96 cycles of CLKOUT). During this time the
CLKOUT remains at 16 kHz.
A
When the activation sequence is completed, the
TDA8002C will be in the active mode. Data is exchanged
between the card and the microcontroller via the I/O lines.
CTIVE MODE
All card contacts are inactive
Oscillator (XTAL) does not operate
The V
detection and OFF output remain functional
Internal oscillator is slowed to 32 kHz, providing 16 kHz
on CLKOUT.
