YES
*5
Read data as described in 13.3-2 or 13.3-3 when it takes (1/1024) sec or more to set the WTEN bit from 0 to 1
(CE=L), the read operation described in 13.3-1 is prohibited as such a case.
*1) to *4) These notes are the same as 13.2 notes *1) to *4).
*5) When needing any higher-order digits than the minute digits, replace
second digits with minute digits. (Reading LSD one of the required digits
twice.)
*6) Select the level mode as an interrupt mode by setting the CT3 bit to 1.
*7) Write 0 to CTFG bit for turning off INTR pin.
*8) Complete read operation within an interrupt cycle after interrupt genera-
tion. (e.g. within 1 second)
