Configuring Upper and
Lower Count Limits
The Upper Count Limit must be positive and the Lower Count Limit must be neg-
ative (zero is not allowed as Count Limit). To set the Maximum and Minimum
Count Limits refer to the following:
Configuring Error-Code
Generation
To configure Overflow/Underflow Error Code Generation for a Linear Counter refer
to the following:
Reporting Overflow and
Underflow
An Overflow or Underflow of a Linear Counter is reported in the corresponding bits
in CIO.

Lower Count Limit
Set Upper Count Limit for Linear Counters between 00000001
H
and 7FFFFFFF
H
. By default
(=00000000
H
) the Upper Count Limit is equal to 7FFFFFFF
H
. Set Lower Count Limit for Linear
Counters between 80000000
H
and FFFFFFFF
H
. By default (=00000000) the Lower Count Limit is
equal to 80000000
