SLOW Minutes contents advance at a 2Hz rate. BOTH Minutes contents advance at a 60Hz (Note 3) rate. FAST Minutes contents advance at a 60Hz (Note 3) rate. SLOW Minutes contents advance at a 2Hz rate. BOTH AM 12:00 is set when in the 12–hour display mode. 0:00 is set when in the 24–hour display mode. FAST 00 seconds is set. No carry to minutes is generated. SLOW Seconds counting is stopped (Held). BOTH (When in the 12–hour display mode) the real time counter is set to AM 12:00. (When in the 24–hour display mode) the real time counter is set to 0:00. FAST Minutes contents advance at a 60Hz (Note 3) rate. SLOW Minutes contents advance at a 2Hz rate. BOTH Minutes contents advance at a 60Hz (Note 3) rate. Note 3. For 50Hz use, 50Hz shall apply. Note 4. Both means that 2 input pins of FAST and SLOW are set to “H”.
