(9) Day count register (RC1DAY)
The RC1DAY register is an 8-bit register that takes a value of 1 to 31 (decimal) and indicates the count value of
days.
It counts up when the hour counter overflows.
This counter counts as follows.
When data is written to this register, it is written to a buffer and then to the counter up to 2 clocks (32.768 kHz)
later. Set a decimal value of 00 to 31 to this register in BCD code.
This register can be read or written in 8-bit units.
Reset sets this register to 01H.
Caution Setting a value other than 01 to 31 to the RC1DAY register is prohibited. Setting a value
Remark
• 01 to 31 (January, March, May, July, August, October, December)
• 01 to 30 (April, June, September, November)
• 01 to 29 (February in leap year)
• 01 to 28 (February in normal year)
RC1DAY
outside the above-mentioned count range, such as “February 30” is also prohibited.
See 11.4.1 Initial settings, 11.4.2 Rewriting each counter during clock operation, and 11.4.3
