The HOUR register value is set to 12-hour display when the AMPM bit is “0” and to 24-hour display when the AMPM bit
In 12-hour display, the fifth bit of the HOUR register displays 0 for AM and 1 for PM.
(9) Day count register (DAY)
The DAY 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.
• 01 to 31 (January, March, May, July, August, October, December)
• 01 to 30 (April, June, September, November)
• 01 to 29 (February, leap year)
• 01 to 28 (February, normal year)
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.
Even if the hour count register overflows while this register is being written, this register ignores the overflow and is
set to the value written. Set a decimal value of 01 to 31 to this register in BCD code.
DAY can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 01H.
