Note The RCLOE0 and RCLOE2 bits must not be enabled at the same time.
Caution If the RCLOE0 and RCLOE1 bits are changed when RTCE = 1, the last waveform of the 32.768 kHz
Remark ×: don’t care
• Rewrite the AMPM bit value after setting the RWAIT bit (bit 0 of real-time counter control register 1 (RTCC1)) to 1.
• Table 9-2 shows the displayed time digits that are displayed.
When changing the values of the CT2 to CT0 bits while the counter operates (RTCE = 1), rewrite the values of the
CT2 to CT0 bits after disabling interrupt servicing INTRTC by using the interrupt mask flag register. Furthermore,
after rewriting the values of the CT2 to CT0 bits, enable interrupt servicing after clearing the RIFG and RTCIF flags.
RCLOE0
If the AMPM bit value is changed, the values of the hour count register (HOUR) change according to the specified
time system.
