Double multiprotocol IC card interface
TDA8007B
Thetime-outcounterisveryusefulforprocessingtheclock
counting during ATR, the Work Waiting Time, or the
waiting times defined in T = 1 protocol. It should be noted
that the 200 and 400 CLK counter used during ATR is
done by hardware when the start session is set; a specific
hardware controls functionality BGT in T = 1 protocol, and
a specific register is available for processing the extra
guard time.
The possible use of the counters is as follows:
ATR (cold reset):
– Before activation; TOR1 = C0H, TOR2 = 6EH,
TOR3 = 0andTOC = 65.Onceactivated,timer 2 + 3
will count 40920 clock pulses before giving an
interrupt.
– On interrupt; TOR2 = 76H and TOC = 65. If a
character is received from the card before the
timeout,thencounter 1willbeenabled.Counter 1will
give one interrupt every 192 ETUs, so the software
will count 100 times to verify that the ATR is finished
before 19200 ETUs. The UART will give an interrupt
with bit Buffer Full (BF) at 10.5 ETUs after the start
bit.
– On interrupt; TOR3 = 25H, TOR2 = 80H and
TOC = 65. Counter 1 keeps on counting
100

192 ETUs, while counter 2 and 3 counts
9600 ETUs. This sequence is repeated until the
character before the last one of the ATR.
– On interrupt TOR3 = 25H, TOR2 = 80H and
TOC = E5. Timer 1 will be automatically stopped at
the end of the last character of the ATR, allowing a
count of 19200 ETUs.
– On interrupt TOC = 00.
Work Waiting Time (WWT) in T = 0 protocol;
– Before sending the first command to the card
TOR1, TOR2 and TOR3 should be loaded with the
correct 960

D value and TOC = 7C
– Timer 3, 2 and 1 will count the WWT between each
start bit
Character Waiting Time (CWT) and Block Waiting Time
(BWT) in T = 1 protocol:
– Before sending the first block to the card, TOR3,
TOR2and TOR1should beloadedwith the CWTand
TOC = 7C
– Timer 3 + 2 + 1 will count the CWT between each
start bit
– Before the end of the block, TOR3, TOR2 and TOR1
should be loaded with the BWT
– Timer 3 + 2 + 1 will count the BWT from the last start
bit of the sent block
– After reception of the first character of the block from
the card, TOR3, TOR2 and TOR1 should be loaded
with the CWT
– Timer 3 + 2 + 1 will count the CWT between each
received start bit
– And so on.
Before and after CLOCK STOP (example, where
ETU = 372 clock pulses):
– After the last received character on I/O, TOR3 = 0,
TOR2 = 6 and TOC = 61
– Timer 3 + 2 will start counting 2232 clock pulses
before giving an interrupt
– On interrupt, the software may stop the clock to the
card
– When it is necessary to restart the clock, TOR3 = 0,
TOR2 = 2, TOC = 61 and restart the clock
– Timer 3 + 2 gives an interrupt at 744 clock pulses,
and then the software can send the first command to
the card.
ISO UART
REGISTERS
When the microcontroller wants to transmit a character to
the selected card, it writes the data in direct convention in
the UART Transmit Register (see Table 8). The
transmission:
Starts at the end of writing (on the rising edge of WR) if
the previous character has been transmitted and if the
extra guard time has expired; or
Starts at the end of the extra guard time if this one has
not expired; or
Does not start if the transmission of the previous
character is not completed.
In the case of a synchronous card (bit SAN within UCR2
is set), only D0 is relevant, and is copied on the I/O of the
selected card. When the microcontroller wants to read
data from the card it reads it from the UART Receive
Register (see Table 9) in direct convention.
In case of a synchronous card, only D0 is relevant and is a
copy of the state of the selected card I/O.
When needed, this register may be tied to a FIFO whose
length ‘n’ is programmable between 1 and 8.
If n > 1, then no interrupt is given until the FIFO is full. The
microcontroller may empty the FIFO at any time.
