Notice in the preceding example that “0XE000” indicates that control bits EN, TT
and DN are set to one.
Enter the contRol (R) data values in the following order: CTL, LEN and POS. The
import utility does not prevent undefined control bits from being set. Providing data
for undefined control bits does not affect a program.
The control word (CTL) defines the control bits for timers (T), counters (C) and
control (R) file. See tables 5.S, T, and U.
