Symbol
Note RCLOE0 and RCLOE2 must not be enabled at the same time.
Caution If RCLOE0 and RCLOE1 are changed when RTCE = 1, a glitch may be generated on the
Remark
After changing the values of CT2 to CT0, clear the interrupt request flag.
RCLOE0
To change the value of AMPM, set RWAIT (bit 0 of RTCC1) to 1, and re-set the hour count register (HOUR).
Table 10-2 shows the displayed time digits that are displayed.
