Checking the counter function
In order to check the counter function, a message MSG_CNTx_FQE = 1 can be generated
(
→
see page 30),
•
if,
after a defined time-out-time in
REG_CNTx_TO
,
the period duration measurement has not been finished, yet,
• or
if
the measured value in
REG_CNTx_MV
is > 0×FF FF FF FF.
If the time-out-time in
REG_CNTx_TO
= 00 00 00 00 (default-setting), then the message
generation in
MSG_CNTx_FQE
is switched off.
Note
If REG_CNTx_DIV = 0,
then the value is transferred and an error bit is set.
The calculation of measurement values is stopped and REG_CNTx_MV is set to "0".
