KEEP(11) is used to maintain the status of the designated bit based on two

execution conditions. These execution conditions are labeled S and R. S is the

S and reset by R.

When S turns ON, the designated bit will go ON and stay ON until reset, regard-

less of whether S stays ON or goes OFF. When R turns ON, the designated bit

will go OFF and stay OFF until reset, regardless of whether R stays ON or goes

OFF. The relationship between execution conditions and KEEP(11) bit status is

shown below.
