11.3
The RTC has the following registers.
• Second data register (RSECDR)
• Minute data register (RMINDR)
• Hour data register (RHRDR)
• Day-of-week data register (RWKDR)
• RTC control register 1 (RTCCR1)
• RTC control register 2 (RTCCR2)
• Clock source select register (RTCCSR)
• Extended module stop register (EXMDLSTP)
11.3.1
RSECDR counts the BCD-coded second value. This register is initialized to H'00 by a STBY input
or the RST bit in RTCCR1, but not initialized by a RES input. The setting range is decimal 00 to
59. For more information on reading seconds, minutes, hours, and day-of-week, see section 11.4.2,
Time Data Reading Procedure.
