Table 207 Status information scaler part; 8FH[7:0]; read only register
Note
1. Status information is unsynchronized and shows the actual status at the time of I
18.2.5.5
Table 208 Task handing control; register set A [90H[7:6]] and B [C0H[7:6]]; note 1
Note
1. X = don’t care.

Output field ID is field ID from scaler input
Output field ID is task status flag, which changes every time an selected task
is activated (not synchronized to input field ID)
Scaler SAV/EAV byte bit 7 and task flag = 1, default
Scaler SAV/EAV byte bit 7 and task flag = 0
Active task is carried out directly
1 field is skipped before active task is carried out
... fields are skipped before active task is carried out
6 fields are skipped before active task is carried out
7 fields are skipped before active task is carried out

EVENT HANDLER CONTROL
status on input pin XTRI, if not used for 3-state control, usable as hardware flag for software
use
status on input pin ITRI, if not used for 3-state control, usable as hardware flag for software
use
status of the internal ‘FIFO almost filled’ flag
status of the internal ‘FIFO overflow’ flag
copy of bit DPROG, can be used to detect power-up and start-up fails
error flag of scalers output formatter, normally set, if the output processing needs to be
interrupted, due to input/output data rate conflicts, e.g. if output data rate is much too low and
all internal FIFO capacity used
status of the field sequence ID at the scalers input
status of the field sequence ID at the scalers output, scaler processing dependent
