There are only three named status bits in an A-B Timer status word.
Bit 13 is Timer Done /DN
Bit 14 is Timer Timing /TT
Bit 15 is Timer Enabled /EN
1747-RM001, page 2-9 is the authoritative reference on the state of each bit at each state of the Timer instruction and in each Controller execution mode (Program, Run, and First Scan).
