Chapter 4 Module Configuration, Output, and Input Data
Current Count (Ctr[n].CurrentCount)
This is the 32-bit count value from the counter.
Stored Count (Ctr[n].StoredCount)
This is the last stored 32-bit value from counter (
n). The count value is stored
depending on the Ctr
nConfig.StorageMode and Zn inputs.
When a storage event occurs, the Ctr[
n].RisingEdgeZ bit is set, indicating that
the value is new. If more than one Z
n occurs before the Ctr[n].RisingEdgeZ bit is
reset (using the Ctr
nResetRisingEdgeZ bit), the Ctr[n].StoredCount word will
contain only the last Ctr[
n].StoredCount value. There is no indication that the
data has been overwritten.
