EOC=25
This input indicates that the EOC code 25h (stop) was
received from the U-interface.
8
EOC=27
This input indicates that the EOC code 27h (go) was
received from the U-interface.

T1 set
An internal 500 micro seconds timer is enabled.
The 500 micro seconds timer (see 9) has expired.
10
11
T1 expired
TD1 set
An internal timer TD1 is enabled. The length of this timer
