CLEN
(For read/write)
*
1) The “
*
” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*
2) (CLEN) control bit for 32kHz output
The CLEN bit is set to 0 when the XSTP=1. CLEN is not writable and set to 0 when CLKC pin level low/open.
*
3) 32KOUT condition
2.6 32kHz control register (BANK 1, at Ah)
3. Counters
3.1 Clock counter (BANK 0, at 0h-5h)
*
1) The “
*
” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*
2) Any carry to 1-second digits from the second counter is disabled when the WTEN bit (of the control register 1) is set to 0.
*
3) Time digit display (BCD code):
Second digits: Range from 00 to 59 and carried to minute digits when incremented from 59 to 00.
Minute digits : Range from 00 to 59 and carried to hour digits when incremented from 59 to 00.
Hour digits
: Range as shown in the section on the 12/24 bit and carried to day and day-of-the-week digits when incremented from 11 p.m. to 12
a.m. or 23 to 00.
*
4) Any registered imaginary time should be replaced with actual time as carrying to such registered imaginary time digits from lower-order ones cause
the clock counter to malfunction.
