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 CtrnConfig.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 Zn occurs before the Ctr[n].RisingEdgeZ bit is
reset (using the CtrnResetRisingEdgeZ 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.
