ENERAL REGISTERS
The Card Select Register (see Table 1) is used for
selecting the card on which the UART will act, and also to
reset the ISO UART.
If SC1 = 1, then card 1 is selected; if SC2 = 1, then card 2
is selected, if SC3 = 1, then card 3 is selected. These bits
must be set one at a time. After reset, card 1 is selected by
default. The bit Reset ISO UART (RIU) must be set to
logic 1 by software before any action on the UART can
take place. When reset, this bit resets all UART registers
to their initial value.
It should be noted that access to card 3 is only possible
once either card 1 or 2 has been activated.
The Hardware Status Register (see Table 2) gives the
status of the chip after a hardware problem has been
detected.
Presence Latch 1 (PRL1) and Presence Latch 2 (PRL2)
are HIGH when a change has occurred on PR1 and PR2.
SupervisorLatch(SUPL)isHIGHwhenthesupervisorhas
been activated.
Protection 1 (PRTL1) and Protection 2 (PRTL2) are HIGH
when a default has been detected on card readers 1
and 2. (PRTL is the OR function of protection on V
CC
and
RST).
PTL is set if overheating has occurred.
INTAUXL is HIGH if the level on the INTAUX input has
been changed.
When PRTL2, PRTL1, PRL2 or PRL1 or PTL is HIGH,
then INT is LOW. The bits having caused the interrupt are
cleared when the HSR has been read-out. The same
occurs with bit INTAUXL if not disabled.
At power-on, or after a supply voltage dropout, SUPL is set
and INT is LOW. INT will return HIGH at the end of the
alarm pulse on pin RSTOUT. SUPL will be reset only after
a status register read-out outside the ALARM pulse
(see Fig.7).
In case of emergency deactivation (by PRTL1, PRTL2,
SUPL, PRL2, PRL1 or PTL), the START bit is
automatically reset by hardware.
The three registers TOR1, TOR2 and TOR3 form a
programmable 24-bit ETU counter, or two independant
counters (one 16-bit and one 8-bit).
The value to load in TOR1, 2 and 3 is the number of ETUs
to count.
The TOC register is used for setting different
configurations of the time-out counter as given in Table 7
(all other configurations are undefined).

Card select register (write and read); address: 0
(all significant bits are cleared after reset, except for SC1 which is set)
Table 2
Hardware status register (read only); address: F
(all significant bits are cleared after reset, except for SUPL which is set within the RSTOUT pulse)
Table 3
Time-out register 1 (write only); address: 9 (all bits are cleared after reset)
