This function is NOT available for this module.
The value is invalid or out of range.
No response from the module. Communication timeout.
HWCONFIG configuration error. Instruction stops.
There is no such counting channel for the HC module.
Input interface not selected. Instruction stops.
Invalid value in Action
One of the counting channel of the HC module is executing counting. Other channels cannot
perform the same task at the same time.
Remarks
In HWCONFIG you can set the option to detect or not to detect.
(default: detection disabled)

Cause of the error: when either overflow (>2
(<-2 )
Ways to clear the error: use the DHCCNT instruction to
reset/preset or execute RESET by the Z phase.
Cause of the error: the value of the linear counter exceeds the
user-defined range
Ways to clear the error: when the value of the linear counter is
within the user-defined range
Note: when the counting value exceeds the upper or lower limit,
the value will keep as the value in upper/lower limit. After the
values return to the acceptable range, the counting continues.
Cause of the error: even if the value of the linear counter
exceeds the user-defined range, the hardware counter

continues counting. But if the hardware counter counting is

stops. After clearing the error, the counting resumes.
Ways to clear the error: use the DHCCNT instruction to
