Read or write anytime.
These eight pairs of control bits are encoded to specify the output action to be taken as a result of a
successful OCn compare. When either OMn or OLn is one, the pin associated with OCn becomes an
output tied to OCn regardless of the state of the associated DDRT bit.
Read or write anytime.
These eight pairs of control bits configure the input capture edge detector circuits.
