Note RCLOE0 and RCLOE2 must not be enabled at the same time.
Caution If RCLOE0 and RCLOE1 are changed when RTCE = 1, the last waveform of the 32.768 kHz and 1
Remark ×: don’t care
• To change the value of AMPM, set RWAIT (bit 0 of RTCC1) to 1, and re-set the hour count register (HOUR).
• Table 7-2 shows the displayed time digits that are displayed.
When changing the values of CT2 to CT0 while the counter operates (RTCE = 1), rewrite the values of CT2 to CT0
after disabling interrupt servicing INTRTC by using the interrupt mask flag register. Furthermore, after rewriting the
values of CT2 to CT0, enable interrupt servicing after clearing the RIFG and RTCIF flags.
