Operating mode
All counters are stopped.
Counters 2 and 3 are stopped; counter 1 continues to operate in auto-reload mode.
Counter 1 is stopped, and counters 3 and 2 form a 16-bit counter. Counting the value stored in registers TOR3
and TOR2 is started after 61h is written in register TOC. When the terminal count is reached, an interrupt is
given, and bit TO3 in register USR is set. The counter is stopped by writing 00h in register TOC, and should be
stopped before reloading new values in registers TOR2 and TOR3.

The time-out counter is very useful for processing the clock counting during ATR, the
Work Waiting Time (WWT) or the waiting times defined in protocol T = 1. It should be
noted that the 200 and n
for TDA8029HL/C2) used during ATR is done by hardware when the start session is set.
Specific hardware controls the functionality of BGT in T = 1 and T = 0 protocols and a
specific register is available for processing the extra guard time.
Writing to register TOC is not allowed as long as the card is not activated with a running
clock.
Before restarting the 16-bit counter (counters 3 and 2) by writing 61h, 65h, 71h, 75h, F1h
or F5h in the TOC register, or the 24-bit counter (counters 3, 2 and 1) by writing 68h or 7C
in the TOC register, it is mandatory to stop them by writing 00h in the TOC register.
Detailed examples of how to use these specific timers can be found in application note
“AN01010” .
