Function Table B:
Display Mode Real Time Display Time Setting Input Pin FAST SLOW BOTH FAST Alarm Display SLOW BOTH FAST Seconds Display SLOW BOTH FAST Sleep Display SLOW BOTH Function Minutes contents advance at a 60Hz (Note 3) rate. Minutes contents advance at a 2Hz rate. Minutes contents advance at a 60Hz (Note 3) rate. Minutes contents advance at a 60Hz (Note 3) rate. Minutes contents advance at a 2Hz rate. AM 12:00 is set when in the 12-hour display mode. 0:00 is set when in the 24-hour display mode. 00 seconds is set. No carry to minutes is generated. Seconds counting is stopped (Held). (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. Minutes contents advance at a 60Hz (Note 3) rate. Minutes contents advance at a 2Hz rate. 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".
