Retried the reading since a carry occurred during the operation.
Do this process within the following time requirements
by combination between t1 and t0.
t1=0, t0=1
within 1 second
t1=1, t0=0
within 1 minute
t1=1, t0=1
within 1 hour
TIME DATA READ
See Note below
REGISTER CD READ
Normal read
(Note)
Reading method 2 in the case of not using HOLD bit
t1=0 and t0=1 when required to a unit of second
t1=1 and t0=0 when required to a unit of minute
t1=1 and t0=1 when required to a unit of hour

The reason why the registers are read
twice is to avoid the case during the
variation of information because a
carry has occurred accidentlly.
