RTCNT is an 8-bit counter that increments using the clock selected by bits CKS[2:0] in RTCSR.
When RTCNT matches RTCOR, RTCNT is cleared to 0. The value in RTCNT returns to 0 after
counting up to 255. When the RTCNT is written, the upper 16 bits of the write data must be
H'A55A to cancel write protection.
