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.
