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

Second Data Register (RSECDR)

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.
