RTCC0
Symbol
Note RCLOE0 and RCLOE2 must not be enabled at the same time.
Caution If RCLOE0 and RCLOE1 are changed when RTCE = 1, glitches may occur in the 32.768 kHz
Remark ×: don’t care
Rewrite the AMPM value after setting RWAIT (bit 0 of RTCC1) to 1. If the AMPM value is changed, the values of
the hour count register (HOUR) change according to the specified time system.
Table 7-2 shows the displayed time digits.
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.
