It counts on the carry generatedonce per second by the RTC.R64CNT counter.The setting range is decimal 00 to 59. The RTC will not operate normally if anyother value is set. Write processing should be performed after stopping the countwith the START bit in RTC.RCR2, or by using the carry flag.D R A FTRTC.RSECCNT is not initialized by a power-on or manual reset, or in standby mode.Bit 7 is always read as 0. A write to this bit is invalid, but the write value shouldalways be 0.SuperH, Inc.SH-5 System Architecture, Volume 1: System 05-SA-10001 v1.0
