D2 = 1 specifies PM, D2 = 0 specifies AM, D3 = 1 specifies 24-hour timer, and
D3 = 0 specifies 12-hour timer.
When D3 = 1 is written, the D2 bit is reset inside the IC.
The D2 and D3 bits in D10 are used to select a leap year.
A selector to reset 5 poststages in the 1/215 frequency divider and the BUSY
circuit. They are reset when this code is latched with ADDRESS LATCH and
the WRITE input goes to 1.
A selector to obtain reference signal output. Reference signals are output to
D0 – D3 when this code is latched with ADDRESS LATCH and READ input
goes to 1.

There are no bits in blank fields for data input/output. 0 signals are output by reading and data is
not stored by writing because there are no bits.
The bit with marked
*
is used to select the 12/24-hour timer and the bits marked
*
are
used to select a leap year. These three bits can be read or written.
When signals are input to bus lines D0 – D3 and ADDRESS WRITE goes to 1 for address input,
ADDRESS information is latched with ADDRESS LATCH.
